Calibration Procedure

Recalibrate your meter:

It is recommended that the multimeter be calibrated once each year.

1.Perform calibration at an ambient temperature of 23°C±2°C and a relative humidity of <70% Disconnect the test leads and turn the meter off. Remove the test leads from the front terminals.

2.Position the meter face down. Remove the battery cover screw and the 2 bottom case cover screws.

3.Lift the end of the bottom case cover until it gently unsnaps from the case top at the end nearest the LCD.

(A)DC V Calibration (Adjust VR1)

1. Set the rotary switch to position “ ” for the DC Volts function.

2. Set the output of DC calibrator for 300.0mV and connect to

and COM input terminals on

meter.

3.Using a small flat-tipped screwdriver, adjust VR1 until the display reads 299.5 to 300.5mV

4.Disconnect the DC calibrator from the meter.

(B)AC V Calibration (Adjust VR2) Model 61-340:

1.

Set the rotary switch to position. “

” for the AC Volts function.

 

2.

Set the output of the calibrator for 3.000V at 60Hz and connect to

and COM input

 

terminals on meter.

 

 

3.Using a small flat-tipped screwdriver, adjust VR2 until the display reads 2.995 to 3.005Volts

4.Disconnect the AC calibrator from the meter.

Model 61-342:

 

 

1.

Set the rotary switch to position. “

” and press SELECT button to

select AC A function,

 

then press RANGE button to select

10A range .

 

2.

Using a small flat-tipped screwdriver, adjust VR4 until the display reads 0 to 3 digits.

3.

Press RANGE button to select 4A

range and adjust VR5 until the display reads same as the

 

digits at AC 10A range ( 0 to 3 digits)

 

4.

Set the rotary switch to position. “

” for the AC Volts Function.

 

5.

Set the output of the calibrator for 3.000V at 60Hz. and connect to

and COM input

 

terminals on meter.
