Basic Maintenance
Warning
To avoid shock, remove the test leads and any input signals before opening the case or replacing the battery.
Opening the Meter Case
Caution
To avoid unintentional shock circuit, always place the uncovered Meter assembly on a protective surface.
When the case of the Meter is open, circuit connections are exposed.
To open the Meter case, do the following:
Replacing the Battery
Low battery indication
The Meter powered by 9V battery.
To replace the battery refer to figure.
1. Disconnect test leads from any live source, switch off the meter.
2. Remove the back case by using a flat-blade screwdriver to turn the screws counter-clockwise.
Page 13
Testing Fuses
To test the internal fuses of the meter.
1. Turn the rotary switch to the Ω position.
2. To test FUSE 71 (Bussmann DMM-B-11A recommended), plug a test lead into VΩHz input terminal,
and use the probe to touch the A input terminal. The display should indicate between 0.0 to 0.3Ω.
3. To test FUSE 72 (Bussmann DMM-B-44/100 recommended), plug a test lead into VΩHz input
terminal, and use the probe to touch the mA input terminal. The display should indicate between 0.0
to 2.5Ω.
4. If display reading is higher than the range, replace the fuse.
Fuse Replacement
Refer to the following figure to replace fuse:

The following performance tests verify the complete operability of the Meter and check the accuracy of each
Meter function against the Meter’s specifications.
Accuracy specifications are valid for a period of one year after calibration, when measured at an operating
temperature of 18°C to 28°C and a maximum of 80% relative humidity.
To perform the following tests, it is not necessary to open the case, no adjustments are necessary, merely
make the required connections, apply the designated inputs, determine if the reading on the Meter display
falls within the acceptable range indicated.
If the Meter fails any of these tests, it needs calibration adjustment or repair.
Testing the Voltage Function
To verify accuracy in the AC and DC voltage ranges, do the following:
1. Turn on the meter, and turn the rotary switch to the correct position.
2. Connect the Calibrator to the VΩ and COM inputs on the Meter.
3. Set the Calibrator for the voltage and frequency from step 1 to 20 in Table 1.
4. Compare the reading on the Meter display with the reading shown in Table 1.
5. If the display reading falls outside of the range shown in Table 1, the Meter does not meet
specification.

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 within 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 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.
