WARNING LAMP
According to EN 50191 the highest level of safety must be undertaken when working with high voltages
like used in DIELECTRIC test. For this purpose the FULLTEST 3 offers an output to drive the high
voltage warning lamp. Use only the lamps supplied by original supplier of the FULLTEST 3 tester.
CAUTION
 Always connect COM terminal to GND if measured UUT is grounded,
otherwise possible capacitive leakage current may flow to ground which may
disturb the measurement!
 Measurement time in MANUAL mode is limited to 60 min!
The following specific information can be shown on the display during measurement:
