High Voltage Warning (HI-V):
The meter beeps and lights an LED when >30V AC/DC voltage is present through test leads of the meter. This enhanced safety feature alerts the user that dangerous voltage is present across the leads even if the meter is set on an incorrect function or range. Notes: This feature does not work through the clamp head as the clamp is intended to only measure current. Audible indication can be turned off by pressing and holding the MAX/MIN button while turning the function switch from OFF to the desired range position.

CALIBRATION
Calibration Preparation 1. Turn on the calibrator, allow calibrator to warm up. Perform calibration at
23±2°C (73.4°F ±3.5°F) at relative humidity of < 70%. Temperature stabilization should be reached after 30 minutes. 2. Disconnect the test leads and turn the range switch to “OFF”. 3. Remove the screws holding the battery cover, one at the jaw, and the screw for the TightSightTM cover. 4. Remove the case bottom using care not to damage the leads of battery snap and spring to the continuity beeper. (Beeper is attached to the bottom case cover.) 5. Using a calibrated meter ensure the battery measures a minimum of 7.5V DC. If the battery measures under 7.5V DC, replace the battery (see Battery Replacement page 9).
Calibration Procedure It is recommended that all IDEAL meters undergo the following calibration procedure on an annual basis. The class of calibrator or equipment should have an accuracy that exceeds, by an expectable ratio the accuracy of this instrument.
Auto Calibration: Set the short circuit 2-pin connector, mounted on PC board, from J2 to J1 position. Replace the case bottom of the meter. It is allowed to do calibration for any one of the following functions individually that is inaccurate. There is no need to do calibration for all functions.
V AC Calibration 1. Set Function Switch from OFF to ACV position. 2. 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 000.0V ± 1 digit. Zero adjustment is complete. 3. Connect the calibrator to the V and COM inputs on the meter. 4. Output AC 50V/50Hz. After a reading in the LCD is settled (about 5 seconds), press MAX/MIN button until unit display reads 48V ~ 50V. Adjustment is complete. 5. Output AC 500V/50Hz. After a reading in the LCD is settled (about 5 seconds), press MAX/MIN button until unit display reads 500.0V ± 2 digits. Adjustment is complete.
V DC Calibration
1. Set the function switch to DCV 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. Connect the calibrator to the V and COM inputs on the meter. 3. Output DC +500V. After a reading in the LCD is settled (about 5 seconds), press MAX/MIN button
until unit display reads 500.0V ± 2 digits. Adjustment is complete.
Continuity Calibration 1. Set the function switch to Continuity 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.

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 61-770 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.
