Note: - If the resistance is 2 1M, it takes several seconds to stabilize. It is normal.

- If the input terminal is in open circuit, overload mark will be displayed on LCD.

- Before measuring resistance, make sure that the power supply has been

switched off and all the capacitors have been discharged.．

Note:

- Meter shows an approximation of diode forward voltage drop

Continuity Test

- If the instrument and test lead reverse connection, the LCD will show "OL".

Diode test

- If the instrument and test lead open circuit, the LCD will show "OL".

3.2 Use

4.7 Audible Continuity

3.2.1 Use the proper function and range for your measurements

4.7.1 Put away the test probe protective cover.

3.2.2 When serving the meter, use the same model number or identical electrical

specification replacement parts

4.7.2 Take test lead from the back box.
4.7.3 Set the function switch to '

' Ω’ position.

3.2.3 When using the probe s keep your fingers behind the finger guards on the unit

3.2.4 Do not input higher than 600V between the two meter’s input terminal to avoid

electric shock and damage to the meter

4.7.4 Press "SELECT button to make the display show “

”

4.7.5 Connect the test lead and test probe across the resistance to be

3.2.5 When the meter working at an effective voltage over 60V DC or 30V AC

(RMS),special care should be taken for there is danger of electric shock

measured.

4.7.6 The buzzer sounds if the resistance of a circuit under test is less than

3.2.6 Disconnect circuit power and discharge all high-voltage capacitors before testing

resistance, continuity and diode

50Ω; it may or may not sounds if the resistance of a circuit under test is

between 50Ω to 120Ω; it does not sound if the resistance of a circuit

3.2.7 Do not testing resistance, continuity and diode with electricity

5. MAINTENANCE

Warning

Do not attempt to repair or service your Meter unless you are qualified
to do so and have the relevant calibration, performance test, and service
information.

5.1.1 Periodically wipe the case with a damp cloth and mild detergent. Do not use

abrasive or solvents.
