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 61-795 contains parts that can be damaged by static discharge. Follow the standard practices for handling static sensitive devices.
Page 2 Required Equipment Required equipment is listed in Table B. If the recommended models are not available, equipment with equivalent specifications may be used. Only qualified personnel should perform repairs or servicing. Table B. Required Equipment Equipment Required Characteristics Calibrator AC Voltage Range: 0-750V ac Accuracy: ±0.04% (Basic) Frequency Range: 10 ~ 500KHz Accuracy: ± 2% Recommended Model Fluke 5500A Calibrator or equivalent DC Voltage Range: 0-1000V dc Accuracy: ±0.
Page 3 PERFORMANCE VERIFICATIONS Perform the following analysis, if the meter conforms to the limits listed in Table 1 the meter is functioning correctly. If the meter does not conform to any of the listed limits, the calibration procedure must be performed. Check the fuse as a BBS, 1A/600V, 10.4*35 (0.41x1.38 inch) UL/CSA, interrupting rating 10kA. Check case, leads, display, etc, for any defects.
Page 4 CALIBRATION Calibration Preparation Required Equipment The class of calibrator or equipment should have an accuracy that exceeds, by an expectable ratio, the accuracy of the instrument under test. Required fixed resistors: 0Ω, 5Ω, 19Ω, 190Ω, 0.0MΩ, 1MΩ, 10MΩ, 100MΩ, 1000MΩ Simulated Test leads. With a total resistance of < .1Ω ±10mΩ or .05Ω per simulated lead. Calibration Procedure It is recommended that all IDEAL meters undergo the following calibration procedure on an annual basis. Calibration 1.
