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.

  • Page 4: Using The Ma Sourcing (Output) Modes

    Using the mA Sourcing (Output) Modes The Calibrator outputs current for calibrating and testing 0 to 20 mA and 4 to 20 mA current loops and instruments. In SOURCE mode, the Calibrator supplies the current. In SIMULATE mode, the Calibrator simulates a 2-wire transmitter in an externally-powered current loop.

  • Page 6: Simulating A Transmitter

    Simulating a Transmitter When simulating the operation of a transmitter, the Calibrator regulates the loop current to a known value selected by you. A 12 V to 28 V loop supply must be available. Insert the test leads as shown below. LOOP CALIBRATOR Press simultaneously once for slow ramp...

  • Page 7: Auto Ramping The Ma Output

    Auto Ramping the mA Output Auto ramping allows you to continuously apply a varying current from the Calibrator to a passive (sourcing) or active (simulate) loop. Your hands remain free to test the transmitter’s response. Press B + C simultaneously to enter the Auto Ramp mode and step to a ramp type.
