ZEN50 - Atlas ZEN Zener Diode Analyser Information:

The Atlas ZEN is ideal for testing Zener diodes (including avalanche diodes), transient suppressors, LEDs and LED strings.

It generates constant current pulses (selectable from 2mA, 5mA, 10mA and 15mA) at voltages from 0V to 50V. So even high voltage Zeners or high voltage LED strings can be tested.

Test currents are supplied in narrow pulses to ensure that the component under test remains at a constant temperature.

The voltage of the part is displayed on the screen together with the test current and also a measure of the component's slope resistance (also known as dynamic impedance).

Includes:
  • ZEN50 Instrument.
  • Fitted flexible test leads with gold plated crocs.
  • Comprehensive illustrated user guide.
  • AAA Alkaline battery.

FAQs


Q Can the ZEN50 be used in-circuit?
A. Not really. Nothing nasty should happen to your Atlas ZEN as it can cope with abuse voltages of ±50V. But your circuit may be exposed to voltages that it is not designed for. Additionally, other circuit effects can influence the ZEN's readings.

Q. Can I test the VF of diodes and LEDs?
A. Yes. You can even test LED strings with a string voltage of up to 50V. Take great care not to connect your LED(s) in reverse though, the test voltages generated by the Atlas ZEN will exceed the maximum reverse voltage for most LEDs.

Q. What about precision voltage references, will it test those?
A. The Atlas ZEN will apply its test currents in short pulses to your component, it then measures the resulting voltage across it. The test current pulses are kept deliberately short (to prevent temperature rise) so some voltage reference ICs may not respond fast enough. We have tested many however with no problem.

Q. How is the slope resistance measured?
A. The Atlas ZEN automatically tests your device over a span of test currents and internally generates a fitted curve. The curve is mathematically differentiated to calculate the slope at your selected test current. This is more accurate than simply averaging the slope between a pair of test currents.

Q. How much voltage is generated by the ZEN?
A. The Atlas ZEN generates voltages of up to 60V in order to be able to test components that require up to around 50V to operate. Both the voltage and current are electronically limited. The voltages are below levels described in the Low Voltage Directive 2006/95/EC.
