Calibration

Environmental Conditions

Perform calibration at an ambient temperature and relative humidity (23°C±2°C and R.H.

≦

80%). Allow the

instrument to sit at this temperature for at least 30 minutes.
The Operation of Calibration Procedure Mode

Activate Calibration Procedure Mode

Press “

Hold

” button while powering up, then press buttons in the following sequence to activate the

calibration procedure mode
Range → Backlight → VoltSense → Hold → Blue → Min Max
. (

The

“Auto” segment will flash while you are in calibration mode. )

Deactivate Calibration Procedure Mode

Turn the meter off to deactivate calibration procedure mode.

Set Meter Model mode

(61-484 and 61-486 61-486 / 61-484)

After Activate Calibration Procedure Mode, Press the “Min Max” button to select the meter model.

Standard Function Calibration

(Voltage, Ampere, Resistance, Diode, Capacitance)



Dial the rotary switch and press the “

Blue

” button to select the measurement mode.



Press the “

Range

” button to select the range which will be calibrated.



Apply the standard signal indicated in the Calibration Adjustment Point Table to the suitable input
terminals.



Once LCD display to stable, Press the “

Hold

” button to confirm the reading.



If the reading is not withi

n a 10% tolerance of the correct reading when pressing the “Hold” button,

the LCD will display “Err”. Press “Hold” button to exit. Meter will need to be returned for repair.

Temperature Calibration



Connect the temperature calibrator to the meter and wait for at 30 minutes



Apply the standard voltage indicated in the Calibration Adjustment Point Table to the input
terminals.



Once the LCD display is stable, Press the “Hold” button to confirm reading.



If the reading is not within a 10% tolerance of the corr

ect reading when pressing the “Hold” button,

the LCD will display “Err”. Press “Hold” button to exit. Meter will need to be returned for repair.
