5-3. How to Make Measurements WARNING 1. To avoid electrical shock hazard and/or damage to the meter, do not measure voltages that might exceed 500V above earth ground. 2. Before using the instrument, inspect the test leads, connectors, and probes for cracks, breaks, or grazes in the insulation. -
Page 11: Ac Voltage Measurement
AC Voltage Measurement 1. Plug the red test lead into the “V W mA” jack and the black lead into the “COM” jack. 2. Set the RANGE switch to the desired ACV position. 3. Connect the test leads to the device or circuit being measured. -
Page 12: Resistance Measurement
Resistance Measurement 1. Plug the red test lead into the “V W mA” jack and the black test lead into the “COM” jack. 2. Set the RANGE switch to the desired W position. 3. If the resistance being measured is connected to a circuit, turn off the power and discharge all capacitors before measuring. - Page 13 Transistor h 1. Set the RANGE switch to the h 2. Determine whether the transistor is an NPN or PNP- type and locate the Emitter, Base and Collector leads. Insert the leads into the proper holes of the socket on the front panel. 3.
