Fluke 345 - Using the Clamp Meter; Initial Setup

Power Quality Clamp Meter
Calibration Verification Procedure
25
Amps Check
Mode: Amps
Input: dc & 60/50 Hz ac signal
Internal Accuracy: ± 1.5 % rdg ± 5 dgts for A > 10.0 A
± 0.2 A for A ≤ 10.0 A
Harmonic Distortion
Harmonic distortion parameters are not checked because they use the same hardware
paths as are used in measurement of amps and volts.
Frequency Check
Mode: Volts Frequency
Input: 2 V 60/50 Hz
Internal Accuracy: ± 0.5 % rdg 40 - 70 Hz
