Loop Calibrator
Instruction Sheet
Introduction
The Fluke 707 Loop Calibrator (hereafter, the Calibrator) is a
compact sourcing and measuring tool. The Calibrator tests current
loops of 0-20 mA or 4-20 mA and measures dc voltage to 28 V. It
comes with a set of alligator-clip test leads, a 9 V alkaline battery,
and this Instruction Sheet.
The Calibrator is a IEC 61010, CAT I 30 V, Pollution Degree 2
instrument. A CAT I instrument is designed to protect against
transients from high-voltage, low-energy sources, like electronic
circuits or a copy machine, for example.

Battery Saver
The Calibrator automatically turns off after 30 minutes of inactivity.
To reduce this time or disable this feature:
1. With the Calibrator OFF, press D.
PSXX is displayed, where XX is the turn-off time in minutes.
OFF means the power saver is disabled.
2. Turn m to decrease or increase the turn-off time.
To disable, turn m until the display shows OFF.
3. The Calibrator resumes normal operation after 2 seconds.
