Yao Tr LCR Esr Tester Transistor Inductance Capacitance Resistance Esr Meter

Features:

6.24 Testing time is about two seconds, only capacity or inductance measurement can cause longer period.

6.25 Software can be configured to enable series of measurements before power will be shut down.

6.26 Selectable facility to calibrate the internal port resistance of port output and the zero offset of capacity

measurement with the selftest . A external capacitor with a value between 100nF and 20µF connected to pin 1

and pin 3 is necessary to compensate the offset voltage of the analog comparator. This can reduce

measurement errors of capacitors of up to 40µF. With the same capacitor a correction voltage to the internal

reference voltage is found to adjust the gain for ADC measuring with the internal reference.

6.27 Display the Collector cutoff current ICE0 with currentless base (10µA units) and Collector residual current

ICES with base hold to emitter level . This values are only shown, if they are not zero (especially for

Germanium transistors).

6.28 Thyristors and Triacs can only be detected, if the test current is above the holding current. Some Thyristors

and Triacs need as higher gate trigger current, than this Tester can deliver. The available testing current is only

about 6mA!

Attention: Allways be shure to discharge capacitors before connecting them to the Tester! The Tester may be

damaged before you have switched it on. There is only a little protection at the ATmega ports.

Extra causion is required if you try to test components mounted in a circuit. In either case the equipment should be

disconnected from power source and you should be shure, that no residual voltage remains in the equipment.
