Temperature Measurements

WARNING: To avoid electric shock, disconnect test leads from any

source of voltage before making a temperature measurement. Be sure

that the thermocouple has been removed before changing to any other

measurement function.

1. Insert the type K thermocouple probe into the V/

Ω/mA and COM jacks.

2. Turn the rotary switch to the

3. Read the temperature on the display.

Continuity Measurements

1. Insert the black test lead banana plug into the negative COM jack and

the red test lead banana plug into the positive V/

Ω/mA jack. Observe

polarity.

2. Turn the rotary switch to the

•))) position.

3. Touch the test probes to the circuit or device under test. If the

resistance is less than approximately 40

Ω the buzzer will sound.

Diode Measurements

1. Insert the black test lead banana plug into the negative COM jack and

the red test lead banana plug into the positive V/

Ω/mA jack.

2. Turn the rotary switch to the

•))) position.

3. Touch the test probes to the diode under test. Forward voltage will

indicate 0.4V to 0.7V. Reverse voltage will indicate “1.

”. Shorted

devices will indicate near 0mV and an open device will indicate “1.

”

in both polarities.

Battery Test

1. Insert the black test lead banana plug into the negative COM jack and

the red test lead banana plug into the positive V jack.

2. Turn the rotary switch to the 1.5V or 9V BAT position.

3. Connect the red test lead to the positive side of the 1.5V or 9V battery

and the black test lead to the negative side of the 1.5V or 9V battery.

4. Read the voltage in the display.
