4. Press any key on the 715 Calibrator. Display should read:
OUTPUT ----- mA
5. The 715 will then reset itself with all segments momentarily being displayed, then
change to:
OUTPUT
The 715 is now out of the CAL mode. Turn the green O key to turn the calibrator off.
715 Calibration (V2.0 and Later)
1. On the 715 Calibrator, hold down the
press and release the
2. The display shows CAL for 1 second and then xxx, where xxx is the number the
times the unit has been through a calibration adjustment. When the two keys are
released, PASS is displayed. One second later, a zero is displayed for the most
significant of the three digit password. The 715 password is 517. Use the two small
arrows to change the number. After setting each digit, press
entry was correct, 715 will go into calibration mode and the letter "K" will appear on
the display. If the password was wrong, 715 will go into normal operation mode.
3. The calibration will be performed in the following order:
V INPUT
mV INPUT
mA INPUT
V OUTPUT
mV OUTPUT
mA OUTPUT
V INPUT
1. In V INPUT mode, the unit displays "CAL 0" for 1 second followed by the input
voltage using the default calibration.
2. Connect the test leads from the 5520 main Jacks to the V and COM and source 0.0 V.
The unit should read 0.000V +/- 0.010V.

3. Press
to go to the next calibration point. "CAL 25" will be displayed for 1
second and then the input voltage.
4. Source 25V from the 5520. The unit should read 25.000V with 5% tolerance.
5. Press
A
to complete V INPUT calibration. "CHEC" will be displayed for 1
second. The new calibration constants are applied and the V INPUT calibration can
be checked.
6. Set the 5520 to 0.0 and press mA_% key to go to the next mode.
mV INPUT
1. In mV INPUT mode, the unit displays "CAL 0" for 1 second followed by the input
voltage using the default calibration.
2. Source 0.0 mV from 5520. The unit should read 0.00mV +/- 0.10mV.
3. Press
A
to go to the next calibration point. "C 200" will be displayed for 1 second
and then the input voltage.
4. Source 200mV from the 5520. The unit should read 200.00V with 5% tolerance.
5. Press

to complete mV INPUT calibration. "CHEC" will be displayed for 1
second. The new calibration constants are applied and the mV INPUT calibration can
be checked.
