For Continuity tests, if the resistance is < 150

:

, a tone will sound. 

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 the black test lead banana plug into the negative (COM) jack. 

Insert the 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 

Frequency or  % duty cycle measurements 

1.  Set the rotary function switch to the “VDC/AC,Hz” position.

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

banana plug into the positive V jack. 

3.  Select Hz or % duty with the 

Hz/%

 button. 

4.  Touch the test probe tips to the circuit under test. 

5.

  Read the frequency on the display.

Temperature Measurements 

WARNING: 

To avoid electric shock, disconnect both test probes from any source of 

voltage before making a temperature measurement. 

1.  Set the function switch to  

ć ̧

.

2.  Insert the Temperature Probe into the negative (COM) and the V jacks, making sure to 

observe the correct polarity. 

3.  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). 

4.  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 ch

anging to another measurement function 

Non-Contact AC Voltage Measurements 

1.  Touch the probe tip to the hot conductor or insert into the hot side of the electrical outlet. 
2.  If AC voltage is present, the detector light will illuminate. 

NOTE

: The conductors in electrical cord sets are often twisted. For best results, rub the probe tip 

along a length of the cord to assure placing the tip in close proximity to the live conductor.

WARNING: 

 Risk of Electrocution. Before use, 

always test the Voltage Detector on a known live 

circuit to verify proper operation 

NOTE

: The detector is designed with high sensitivity. Static electricity or other sources of energy 

may randomly trip the sensor. This is normal operation 

MODE BUTTON 

To select DC/ACV,OHM/ Diode/Continuity/CAP, 

Data Hold Button 

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. 

REL BUTTON 

For DCA and Capacitance Zero & Offset adjustment. 

RANGE BUTTON

When the meter is first turned on, it automatically goes into AutoRanging. This automatically selects the 

best range for the measurements being made and is generally the best mode for most measurements. 

For measurement situations requiring that a range be manually selected, perform the following: 
1.  Press the RANGE button. The “Auto Range” display indicator will turn off, The “Manual Range” 

display indicator will turn on 

2.   Press the RANGE button to step through the available ranges until you select the range you want. 

3. Press and hold the RANGE button for 2 seconds to 

exit the ManualRanging mode and return to AutoRanging. 

Battery Replacement 

1.  Remove the one rear Phillips head screw 

2.  Open the battery compartment 

3.  Replace the Requires One 9V battery 

4.  Re-assemble the meter
