• Before and after hazardous voltage measurements, test the voltage function on a known source such as line voltage to determine proper meter functioning. • Keep your hands/fingers behind the hand/finger barriers (of the meter and the test leads) that indicate the limits of safe access of the hand-held part during measurement. • Inspect test leads, connectors, and probes for damaged insulation or exposed metal before using the instrument. If any defects are found, replace them immediately.
HOLD Press the HOLD button momentarily toggles to hold mode for all of the functions. To release the HOLD feature momentarily press the HOLD button. MAX Press the HOLD button for 1 second or more activates the MAX HOLD feature for the VDC, VAC and ACA functions. To release the MAX HOLD feature press the HOLD button for 1 second or more. r Relative Zero mode Relative Zero mode allows the user to offset the subsequent meter measurements with the displayed reading as the reference value.
AC Current (see Fig. 2) 1. Set the Function Switch to A� position. 2. Select AC current using the SELECT button. 3. Open spring-loaded clamp by pressing the lever on left side of meter. 4. Position clamp around one wire or conductor and release the clamp lever. Make sure that the clamp is entirely closed. The clamp must be positioned around only one conductor. If it is placed around two or more current carrying conductors, the reading is FALSE. 5.
3. Turn off power to the circuit being measured. 4. Free at least one end of the diode from the circuit. 5. Connect the test probes across the diode noting polarity. 6. Read the display. A good diode has a forward voltage drop of about 0.6 V. An open or reverse biased diode will read .0L. Capacitance (see Fig. 3) 1. Set the Function Switch to Ω and press the SELECT button until � is displayed. 2. Connect the test leads: Red to +, Black to COM. 3. Turn off power to the circuit being measured. 4.
