Diode Measurements
5. Insert the black test lead banana plug into the negative COM jack and the red test lead
banana plug into the positive diode jack.
6. Turn the rotary switch to the

8. Touch the test probes to the diode under test. Forward voltage will indicate 0.4V to 0.7V.
Reverse voltage will indicate "OL". Shorted devices will indicate near 0mV and an open
device will indicate "OL" in both polarities.

Capacitance Measurements
WARNING: To avoid electric shock, disconnect power to the unit under test and
discharge all capacitors before taking any capacitance measurements. Remove the
batteries and unplug the line cords.
5. Set the rotary function switch to the cap position.
6. Insert the black test lead banana plug into the negative (COM) jack.
Insert the red test lead banana plug into the positive (V) jack.
7. Touch the test leads to the capacitor to be tested.

Touch the Temperature Probe head to the part whose temperature you wish to
measure. Keep the probe touching the part under test until the reading stabilizes (about 30
seconds).

Read the temperature in the display. The digital reading will indicate the proper
decimal point and value.
WARNING: To avoid electric shock, be sure the thermocouple has been removed before
changing to another measurement function
Data Hold and Backlight
To freeze the LCD meter reading, press the data hold button. The data hold button is
located on the left side of the meter (top button). While data hold is active, the HOLD
display icon appears on the LCD. Press the data hold button again to return to normal
operation.
Note: The HOLD feature will activate when the Backlight is turned on. Press the HOLD key again
to exit Hold.
The backlight function illuminates the display and is used when the ambient light to too low
to permit viewing of the displayed readings. Press the
turn the backlight on and press the button a second time to turn the backlight off.
Manual Ranging
The meter turns on in the autoranging mode. Press the Range button to go to manual
ranging. Each press of the range button will step to the next range as indicated by the units
and decimal point location. Press and hold the Range button for two seconds to return to
autoranging. Manual ranging does not function in the AC Current , Diode and Continuity
