OPERATION 

Before taking any measurements, read the Safety 
Information Section. Always examine the 
instrument for damage, contamination (excessive 
dirt, grease, etc.) and defects. Examine the test leads 
for cracked or frayed insulation. If any abnormal 
conditions exist do not attempt to make any 
measurements

 

Autoranging 

The meter defaults to autorange when you turn it on. In 
autorange, the meter selects the range automatically.  
 

Manually Selecting a Range  

The meter also has a manual range mode. In manual range, 
you select and lock the meter in a range. To manually 
select a range: 
Press [RANGE] button to hold the selected range. 
Subsequently pressing the [RANGE] button will select 
each range in sequence from the lowest to highest range. 
Hold the button for 2 seconds to return to the Autorange 
Mode. 
 

Data Hold Feature  

Press [HOLD] button to toggle in and out of the Data Hold 
mode. In the data hold mode, the " H" annunciator is 
displayed and the last reading is held on the display.  
Press [HOLD] button again to release the hold and current 
readings are once again displayed. 
 

Mode Switch (DC/AC), (

 / / ) 

Press this switch to toggle between DC and AC in the 
voltage measurements. Press this switch to toggle between 
the continuity/diode and ohms modes, if the function 
switch is set to 

 / /  position. 

 
 

Measuring Voltage  

1. Set the Function Switch to " VOLT" position. 
2. Press Mode switch to toggle between "DC" and "AC". 

The "DC" to "AC" mark is displayed. 

3. Touch the probes to the test points. The range will 

change automatically to the level that will display the 
input voltage with best resolution. 

4. The value indicated in the display window is the 

measured value of voltage with proper decimal point and 
annunciator indication. 

 

Measuring Resistance and Testing Continuity 

1. Set the function switch to 

 / /  position. 

2. Turn off power to the circuit under test. External voltage 

across the components causes invalid readings. 

3. To toggle between the ohms/continuity/diode modes, 

press Mode Switch. 

4. Touch the probes to the test points. In ohms, the value 

indicated in the display is the measured value of 
resistance with proper decimal point and annunciator 
indication. In continuity test, the beeper sounds 
continuously, if the resistance is less than approximately 
35

 

Testing Diodes 

1. Set the Function switch to 

 / /  position. 

2. Turn off power to the circuit under test. External voltage 

across the components causes invalid readings. 

3. Press Mode Switch to toggle between the 

ohms/continuity/diode modes   

4. Touch probes to the diode. A forward-voltage drop is 

about 0.6V (typical for a silicon diode). 

5. Reverse probes. If the diode is good, "OL" is displayed. 

If the diode is shorted, a value near 0mV will be 
displayed. 

6. If the diode is open, "OL" is displayed in both 

directions. 

7. Audible Indication: Less than 0.25V.  

Auto Power off 

1. Auto power off: approx. 8 minutes. 
2. After auto power off, press any button to restart the 

meter, and the reading of measurement will be 
maintained in the display. 

 

Cancellation Of Auto Power Off Feature:

 Press and hold 

the (RANGE) button while 

rotating function switch 

from off to any position to turn the meter on. The 
auto power off feature is disabled.

BATTERY REPLACEMENT 

Power is supplied by two button-type  batteries (NEDA 
1166A, IEC LR-44). The " 

  " appears on the LCD 

display when replacement is needed. 
 
 

WARNING 

Before attempting to replace the battery, 
first disconnect the Test Leads from any 
energized circuit. 

 
 
1. Disconnect the test leads from any energized circuit. 
2. Set the Function Switch to OFF. 
3. Remove battery cover screw.  
4. Slide off battery cover and change batteries.   
5. Replace battery cover and screw.
