Resistance Calibration
1. Set the function switch to range. Short the V and COM inputs on the meter. After a reading in
the LCD is settled (about 5 seconds), press MAX/MIN button until unit display reads 000.0 ± 1
digit. Zero adjustment is complete.
2. Connect the calibrator to the V and COM inputs on the meter.
3. Output 800.0 . After a reading in the LCD is settled (about 5 seconds), press MAX/MIN button
until unit display reads 800.0 ± 2 digits. Adjustment is complete.
4. Output 8K . After a reading in the LCD is settled (about 5 seconds), press MAX/MIN button until
unit display reads 8000 ± 2 digits. Adjustment is complete.
Capacitance Calibration
is settled (about 5 seconds), press MAX/MIN button until unit display reads 000.0 ± 1 digit. Zero
adjustment is complete.
2. Plug a 390uF standard capacitor to V and COM inputs. Press MAX/MIN button until unit display
reads 390.0 ± 5 digits. Adjustment is complete.
A DC Calibration (61-765 only)
1. Set the function switch to DCA range. After a reading in the LCD is settled (about 5 seconds), press
MAX/MIN button until unit display reads 000.0 ± 1 digit. Zero adjustment is complete.
2. Set output of the DC calibrator for 7.8A DC and connect it to Coil = 50N = 390.0A DC.
3. Clamp the jaws to the coil = 50N.
4. After a reading in the LCD is settled (about 5 seconds), press MAX/MIN button until unit display
reads 390.0A ± 2 digits. Adjustment is complete.
A AC Calibration
1. Set the function switch to ACA range. When a reading in the LCD is settled (about 5 seconds), press
MAX/MIN button until unit display reads 000.0 ± 1 digit. Zero adjustment is complete.
2. Set output of the AC calibrator for 1.0A/50Hz and connect it to Coil = 50N = 50.0A AC.
3. Clamp the jaws to the coil = 50N.
4. After a reading in the LCD is settled (about 5 seconds), press MAX/MIN button until unit display
reads about 48A ~ 50A. Adjustment is complete.
5. Set output of the AC calibrator for 7.8A AC/50Hz and connect it to Coil = 50N = 390.0A AC.
6. Clamp the jaws to the coil = 50N.
7. After a reading in the LCD is settled (about 5 seconds), press MAX/MIN button until unit display
reads 390.0A ± 2 digits. Adjustment is complete.
Calibration of the 61-760 series is complete.
Remove all leads from the calibrator and equipment.
Open the case bottom again, and set the short circuit 2-pin connector on PC board from J1 back to J2
position, then replace the case bottom of the meter.
Turn the Function Switch from OFF to any position to restart the meter.
