Set the function switch to the Ω
Use the FUNC button to select the diode function
Insert the black test lead banana plug into the negative (common)
jack at the bottom of the meter.
Carefully turn the test lead retracting nut (located at the top of the
meter) clockwise to completely draw out the positive test lead
Touch the test probes to the
diode under test.
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.
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
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
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
, or Resistance Ω while in the Ω
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.
