Operating Instructions

  Read the ENTIRE IMpORTANT SAFETy INFORMATION section 

at the beginning of this manual including all text under 
subheadings therein before set up or use of this product.

Electrical shock can cause death or injury! NEVER TOUCH 

exposed conductors of electricity

.

General Operating Instructions

Note:

 This Meter automatically selects the appropriate range for each 

measurement, as necessary. Manual range selection is not available.

Data Hold

The data hold function keeps the current reading on the Display. To activate data hold:

1.  Press the 

HOLD

 button and current 

reading will be held on the Display. 
The 

 symbol appears.

2.  Press 

HOLD

 again or turn Rotary 

Switch to release the hold.

Measurement Operation

Note:

  Test Lead probes have removable covers for overvoltage 

protection. With covers in place, Test Leads are rated for CAT III 300V 
protection. Exposed probes are rated for CAT II 300V protection.

Ac/Dc Voltage Measurement

Measure AC conductors carrying 
up to 40 VAC, 50-400 Hz and 
up to 300 VAC, 50-60 Hz.

Measure DC conductors 
carrying up to 300 VDC.

WARNING!

  Use caution when working 

near voltages above 30 VAC rms, 
42 VAC peak, or 60 VDC.  Voltages this 
high present a risk of electric shock.    

1.  Turn Rotary Switch to the 

 

position.

2.  Press 

SELEcT

 button to choose 

between AC and DC voltage.

3.  Carefully touch exposed 

conductors with tips of probes. 

4.  Read measured voltage on the Display. 

For AC voltage, polarity is shown.

5.  When testing is complete, turn Rotary 

Switch to 

OFF

 and store Meter.
