1000V CLAMP METER
DIODE TESTING
WARNING
!
• To avoid possible damage to the meter and to the device under test,
disconnect circuit power and discharge all high-voltage capacitors
before testing diodes.
• To avoid electric shock, do not input higher than DC 60V or AC 30V
1. Connect common test lead to the COM terminal, then insert the red test lead to V Ω
terminal. Polarity of red and black test leads is respectively “+” and “-”.
2. Set the function selector to the measurement setting
3. Press
SELECT
until the screen displays
4. Ensure all power is off in the circuit being measured and that all capacitors have been
discharged.
5. Touch test leads to diode. A reading of 500-800mV on the display indicates forward bias,
“OL” indicates reverse bias. An open device will show “OL” in both polarities and a shorted
device will show approximately 0mV.
