DIODE TEST

1. Set the function switch to the Ω position.

2. Use the FUNC button to select the diode function

3. Insert the black test lead banana plug into the negative (common)

jack at the bottom of the meter.

4. Carefully turn the test lead retracting nut (located at the top of the

meter) clockwise to completely draw out the positive test lead

probe.

5. Touch the test probes to the

diode under test.

6. A good diode will indicate

approx. 0.3V (germanium

diodes) to 0.7V (silicon diodes)

for the forward test and “OL”

for the reverse test.

7. A shorted diode will indicate the same value of voltage in both the

reverse and forward test directions. An open diode will indicate

“OL” in both test directions.

DATA HOLD Button

To freeze a displayed reading, press the DATA H button. The reading will

freeze and the D.H display icon will be visible on the LCD. To release the

display, press the DATA H button again. The DH indicator will switch off

and the display will again show real time readings.

MAXIMUM HOLD Button

To display only the highest reading, press the MAX H button. The M.H

display icon will be visible on the display while in the Max Hold mode.

Now, the display will only change when a higher reading than the

displayed reading is encountered. To return to normal operation, press

the MAX H button again (the MH display icon will switch off).

FUNC (Function) BUTTON

The FUNC (function) button is used to select AC or DC while in the

VOLTAGE (V) mode. The FUNC button is also used to select diode ,

Continuity , or Resistance Ω while in the Ω mode.

RANGE Button

The meter automatically selects the optimum range; however, the meter’s

ranges can be selected manually. When using the RANGE button to

manually select a range, start with the highest range and then select

successively lower ranges until the desired range is reached. The

decimal place will move with each press of the RANGE button.

Automatic Power OFF

The meter is equipped with an automatic power off feature to preserve

battery energy. After 15 minutes of inactivity, the meter will automatically

turn off. To turn the meter on again, simply rotate the function switch to

the desired function.
