DIODE AND CONTINUITY

Range

Overload Protection: 250V DC/AC RMS

For continuity test: When the resistance is between 30Ω and 100Ω, the buzzer may sound or

may not sound. When the resistance is more than 100Ω, the buzzer will not sound.

OPERATION INSTRUCTIONS

Measuring Voltage

1. Connect the Black test lead to the COM Jack and the Red test lead to the V Jack.

2. Set the function switch to V~ or V

3. Connect the test leads to the source or load to be measured.

4. Read the LCD display for the polarity of the Red test lead. The result will be a DC

measurement.

NOTE:

a. When measuring in a small range (E.G. mV), the meter may display an unstable reading

when the test leads have not been connected to the load to be measured. It is normal

and will not affect the measurements.

b. To avoid damage to the meter, do not measure a voltage which exceeds 600V for DC or

AC, depending on measurement function.

Measuring AC Current

1. Set the function switch to the AC 200/400A range. If the display indicates one or more

leading zeros, shift to the 2/20Z range to improve the resolution of the measurement.

2. Press the trigger to open the transformer jaws and clamp one conductor only. It is

impossible to make measurements when two or three conductors are clamped at the

same time.

3. The result displayed will be AC Current.

Measuring Resistance

1. Connect the Black test lead to the COM Jack and the Red test lead to the "VΩ" Jack.

(Note: the polarity of the red test lead is positive "+")
