MAKING MEASUREMENT
X�
1. Use the proper function and range for measurements.
2. To avoid possible electrical shock, personal injury or damages to the
Meter, disconnect circuit power and discharge all high-voltage capacitors
before testing resistance and diode.
3. Connecting test leads:
• Connect the common (COM) test lead to the circuit before connecting
the live lead;
• After measurement, remove live lead before removing the common
(COM) test lead from the circuit
4. Symbol “OL” is displayed on LCD when the measurement is out of range.
