Page 1 Introduction Warning To avoid shock or injury, do not perform the verification tests or calibration procedures described in this manual unless you are qualified to do so. The information provided in this document is for the use of qualified personnel only. Caution The 61-770 series contains parts that can be damaged by static discharge. Follow the standard practices for handling static sensitive devices. For additional information about IDEAL INDUSTRIES, INC.
Page 2 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.

Page 5 PERFORMANCE VERIFICATIONS Perform the following analysis; if the meter conforms to the limits listed in Table 1 through 7 the meter is functioning correctly. If the meter does not conform to any of the listed limits the calibration procedure must be performed. Performance Verification Preparation 1. Turn on the calibrator, allow calibrator to warm up. Temperature stabilization should be reached after 30 minutes. 2.

Page 7 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 TightSight™ cover. 4.
Page 8 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 .
Page 9 Battery Replacement (Refer to Figure 1) 1. Disconnect the test leads from any circuit under test and turn off meter. 2. Use a Philips head screwdriver to remove the screws on battery cover. 3. Remove battery from the battery compartment. 4. Install new 9V battery (NEDA #1604). An alkaline type is recommended. 5. Install new battery into compartment using care to install to proper polarity. 6. Reinstall battery cover.
