Page 5: Dc Voltage Measurement
DC VOLTAGE MEASUREMENT 1) Plug the red test lead into the positive socket. 2) Plug the black test lead into the -COM socket. 3) Set the range to the chosen DCV range position. 4) Connect the red test lead to the positive polarity of the circuit tested, and the black lead to the negative. -
Page 6: Resistance Measurement
RESISTANCE MEASUREMENT 1) Plug the test leads into the positive and COM sockets. 2) Place the range selector to the preferred range position. 3) Short the test leads and adjust the resistance dial so the indicator sits at the 0 position. 4) Make sure there is no voltage across the circuit to be tested. -
Page 7: Diode Test
DIODE TEST 1) Set the range selector to the required range position: X1k for 0-150µA, X10 for 0-15mA or X1 for 0-150mA. 2) Connect the diode to the multimeter. i) For forward current tests - connect the ‘N’ terminal of the tester to the positive polarity of the diode, and the ‘P’... - Page 8 TEST RANGE SCALE MULTIPLIER DC Voltage DC 0.1V B 10 x 0.01 0.5V B 50 x 0.01 B 250 x 0.01 B 10 250V B 50 1000V B 250 B 10 x 100 AC Voltage AC 10V C 10 B 50 250V B 250 1000V...
