IMPORTANT

 

  To maintain accuracy of the meter, replace the exhausted  battery 

immediately when the battery symbol “      “  appears on the meter 
display. 

 

  Avoid measuring error from outside interference.  Keep the meter 

away from spark plugs or coil wires. 

 

  Avoid damaging the meter when testing voltage.    Disconnect the test 

leads from the test points before changing functions. 

 

  Do not exceed the limits shown in the table below:

Getting Started 

 

This chapter will help you get started. It describes the basic functions of 
the Meter. 
 

Meter Basics   

1. Digital LCD display 

  Display features: 

1a. Symbols to identify function 

1b. Four character digital display 

 

The digital display  is best for stable 

input. The bar graph is best for rapidly 

changing input. 

 

2. Function buttons 

Press the button to select a function. A 

symbol will display to verify your 

choice. 

 

3. Rotary Function Dial 

Turn this switch to select a function or 

turn the meter OFF. 

 

4. Volts Terminal 

The Red test lead is used to measure Amps, Volts, Ohms, TEMP, Hz, 

RPM, Cap, mS and Dwell.   

The Black test lead is used in the Common (COM) terminal for all tests 

and measurements.
