Operating Basics
Before you take any of the measurements described in
this section, follow these steps to take the best measure-
ments and avoid damaging the meter.
1. For improved accuracy, allow the meter to stabilize for
30 seconds after turning on the power.
2. Disconnect the test leads from the measurement points
when you select or change a measurement function.
3. Observe the safe test lead connections method on page
1–21 when removing the test leads from the meter.
4. Always disconnect power to the circuit when you
measure resistance, capacitors, check diodes, or check
continuity within the circuit.
Unstable or incorrect measurements may be displayed
when the meter is used near a circuit that emits electro-
magnetic waves.
