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.
1. Set the Rotary Function switch to the cap position.
2. Insert Black test lead banana plug into the negative COM jack.
Insert Red test lead banana plug into the positive (V) jack.
3. Touch the test leads to the capacitor to be tested.
4. Read the capacitance value in the display

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 FEATURE
Auto-Ranging is meter's default setting. To deactivate 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 Auto-Ranging. NOTE: Manual ranging does not function in the AC Current,
Diode, and Continuity check functions
BATTERY REPLACEMENT
1. Remove Phillips head screw from back of meter
2. Open battery compartment
3. Replace dead battery with one "9V" battery (NEDA1604, 6F22 006P)
4. Re-assemble the meter
