K Measure News and New Product Releases
Voltage and Current Data Loggers
There are many applications where one needs to log voltage, temperature or power consumption. Examples of these are monitoring the power usage of an appliance such as a fridge or logging the current consumption of an electronic device over an extended period of time in order to calculate realistic battery lifetime. To fill this need K Measure added 2 data loggers to its range of data loggers:
- The VA602-V1-A1 can measure, display and log DC voltage from 0 - 10V with an accuracy of 20mV and DC current from 0 - 24mA with an accuracy of 50uA.
- The VA602-V2-A2 can measure, display and log AC voltage from 0 - 600V with an accuracy of 1V, and together with a current clamp, also AC current from 0 - 24mA with an accuracy of 1%.
Other features are a build-in battery that is charged via the USB port and enough memory and battery capacity to last 3 years (when recording a measurement every hour). The display can show the real-time, minimum or maximum values, they have configurable alarms and the alarms can be used to start recording. They also come with an IP45 rating, magnetic mounting and very easy-to-use software (can be set up in less than 5 minutes).

SeeBox shortlisted for the Innovation for Africa Prize
The SeeBox (Science, Engineering and Education box), designed by K Measure, has been short-listed for the prestigious Innovation for Africa Prize. The SeeBox is sophisticated 6-in-1 test instrument with an ecosystem of applications specifically for training in electronics and science. It makes it possible for a school to offer electronics as an extracurricular subject to their learners without the need for an electronics teacher. The learner will watch a short animated video explaining a basic concept in electronics, after which the learner will apply what he has learner on a playboard, building a specific circuit. The SeeBox will keep record of a student's progress, the videos watched and circuits built.
At the same time the SeeBox is still a professional test instrument offering unparalleled integration of data to the engineer. This integration of test instruments brings about a significant saving in cost, space and time, as well as exceptional possibilities with the integration of data, such as automatic event correlation, predictive measurements, smart analysis of serial buses and programmable triggering. A practical example is: the SeeBox's multimeter readings are integrated with all the other instruments, so an engineer can, for instance, use the current measurement from the multimeter to trigger another instrument to start doing measurements, or even trigger a channel on the power supply to switch a circuit on or off.

Multimeter with Current Clamp
New from K Measure, supplier of test and measurement instruments, is the TC-704 from Twintex, a multimeter with build-in current clamp. It is a handy companion for electricians and electrical engineers that have to measure high currents while also having to measure voltage, resistance, frequency, temperature and even capacitance. And at a cost of only R750 every technician can keep in his toolbox. The clamp can open 35mm and can measure up to 600A and it can measure voltages up to 600V.
The TC-704 offers some advanced features for its price range, like Manual- and Auto Range, Relative Measurement, Data Hold, Auto Power-off, Strong Anti-magnetic and Anti-jamming performance and CE rating and safety design. The temperature probe, which is included in the package, can measure from -40℃ to +750℃. The package includes multimeter probes, batteries, printed manual and temperature probe.
While K Measure's other current clamps can connect to either an oscilloscope or multimeter to measure AC or DC currents of up to 650A, the TC-704 can only measure AC current, up to 600A.

2000V Universal Isolated Front-end Module for Oscilloscopes
K Measure has added a new accessory for all their oscilloscopes to their range of products. The ISFE module from Siglent converts any oscilloscope into a 2000V isolated scope.
The Isolated front-end module offers 2000V (RMS) isolation between channels, 1000V (RMS) isolation between signal and ground and has a max/min input voltage of -600V ~ +600V. It can be powered from any USB port and draws only 200mA. The USB port is also isolated from the channels. Bandwidth is ≤ 1MHz, which is much higher than the typical frequencies of high voltages.
The ISFE can turn a low-cost PC-based oscilloscope into an expensive isolated oscilloscope, at a fraction of the price. This is ideal for people working with mains or higher voltages and even on vehicles where some voltage spikes can go into the 100's of volts.

K Measure adds 50MHz bench-top Arbitrary Waveform Generator (AWG)
Short on the heels of K Measure’s addition of a 10MHz bench-top Arbitrary Waveform Generator (AWG) to their range of test equipment, comes a 50MHz bench-top AWG as well. For a lot of applications out there 10MHz is just a bit too slow.
One of the most popular pieces of test equipment that you'll find on the desk of most electronic engineers and technicians is an AWG because it is used hand-in-hand with an oscilloscope to inject any custom signal into an electronic circuit and measure what comes out.
An AWG can generate a waveform of any shape, which includes the standard Function Generator waveforms (sine, square, pulse, triangle, ramp), mathematical functions (sin(x)/x, exponential, cardiac, etc.), video & audio test waveforms, modulated radio signals (AM, FM, PSK) and random noise. Some AWGs have (optional) software that enables a person to create his own waveforms on a PC. This can be used, for example, to create a "simulated" signal from an electronic circuit before it even exists and feed that signal into another circuit in order to test the second circuit. All K Measure's AWGs include this software in the package, free of charge.
The SDG1050 from Siglent can generate waveforms of up to 50MHz and has 2 independent outputs. It has an easy-to-use user interface, a 3.5" screen and USB-Host, USB-Device and optional GPIB ports for remote control or uploading custom waveforms via flash disk or PC. Furthermore, it offers advanced functions like random noise, frequency sweeping (linear and logarithmic), modulation (AM, FM, PM, FSK, ASK, PWM) and burst mode. It also has a build-in 200MHz frequency counter.

K Measure adds bench-top Arbitrary Waveform Generator (AWG)
One of the most popular pieces of test equipment that you'll find on the desk of most electronic engineers and technicians is a Function Generator or more recently an Arbitrary Waveform Generator (AWG).
The difference between the two being that function generators can provide only a few standard waveforms (usually sine, square, pulse, triangle and ramp) and only up a few MHz. An AWG, on the other hand, is a highly flexible signal source that can generate a waveform of any shape. This includes the standard Function Generator waveforms (sine, square, pulse, triangle, ramp), non-standard functions (sin(x)/x, exponential, cardiac, etc.), compliance test waveforms (video color bar pattern, AM/FM radio tones, encoded communication test signals) and white or pink random noise. Some AWGs have (optional) software that enables a person to create his own waveforms on a PC. This can be used, for example, to create a "simulated" signal from an electronic circuit before it even exists and feed that signal into another circuit in order to test the second circuit.
K Measure has been supplying PC-based test instruments for many years. PC-based waveform generators have the advantage of taking very up little space on the desk and offering a very intuitive user interface via the PC.
However, in a lot of applications a traditional bench-top AWG or Function Generator is required. For instance on a test bench or assembly line where there is no PC available or if the person must have the AWG running while his computer is off.
For this reason K Measure added the HDG1012A to its range of products. The HDG1012A can generate waveforms of up to 10MHz and has 2 independent outputs (a AWG that goes up to 50MHz is also available). It has an easy-to-use user interface, a 3.5" screen and a computer interface for creating and loading custom waveforms. It offers advanced functionality like random noise, frequency & amplitude sweeping and AM & FM modulation. It also offers some innovative features not found in many high-end waveform generators, like the "AB Add" function. It has 32 built-in waveforms.

K Measure adds serial data logger to its range of data-logging products
If you work with or design products that has a RS232 serial port you probably know what it is like having to monitor the data sent over that RS232 port. You have to connect a separate RS232-to-USB adapter to your laptop, connect a break-out adapter to tap into the communications without destroying the data, start up serial comms software on the laptop and hope the battery will last long enough to capture the offending data.
If you can associate with the above scenario K Measure's new serial data logger is just the thing you need. No laptops, software, cables or flat batteries. You simply connect the D9 connector to the SerialGhost, and then it connects to the device whose serial data you want to log. It’s got 2GB of built in memory so you can record the data being send over the RS232 line for a very long time. And when you're done recording data, you simply connect the SerialGhost to your PC's USB port. It mounts as a normal USB flash drive, where you can open the log files with any text editor like Notepad.
• Supports all baud rates up to 115,200 bps.
• Logs both Tx and Rx streams simultaneously.
• Has 2 Gbytes of internal memory.
• Can be powered from a computer's USB port or an external power supply.
• Requires no software or drivers to be installed and is Windows, Linux, and Mac compatible.
Applications include recording data from peripherals like printers, keyboards & mouse, reverse-engineering of protocols and data logging from sensors (e.g. temperature, pressure, voltage).

K Measure equipped the Labs at the University of Johannesburg in 2012
K Measure in 2011 won the tender to equip the electronics student labs at the University of Johannesburg's Auckland Park and Doornfontein campuses. We did our final delivery at the end of last year, and the Elabs has been in use at UJ since the start of 2013. Our collaboration with UJ has resulted in the university now using one unified test instrument to train the electronics students, in stead of the traditional 4 or 5 instruments needed at a typical electronic work station.
