Note
The Calibrator rear-panel CALIBRATION switch does not have to be
enabled for this procedure.
1.
Turn on the Calibrator and let it warm-up for no less than 30 minutes.
2.
Push
.
3.
Push
. This opens the setup menu (see below).
nn068f.eps
4.
Push the CAL softkey. This opens the calibration information menu (see below).
nn069f.eps
5.
Push the CAL softkey. This opens the calibration activity menu (see below). SCOPE
CAL is shown as an option if it is installed:
gvx034.eps
6.
Push the ZERO softkey to zero the Calibrator. Push the OHMS ZERO softkey to zero
only the ohms function. After the zero routine is complete (several minutes), push
to reset the Calibrator. For a complete zero calibration, a short circuit that can
pass 20 A must to be applied between the 20A and AUX LO terminals.
Operate and Standby Modes
When the OPERATE annunciator is illuminated and OPR is shown, the output value and
function shown on the Output Display is live at the selected terminals. When STBY is
shown in the Output Display, most of the Calibrator outputs are open-circuited. The
front-panel thermocouple (TC) terminals are not open-circuited. To start the operate
mode, push
. To put the Calibrator in standby, push
.
If the Calibrator operates and these things occur, the Calibrator automatically goes to the
standby mode:
•
is pushed.
•
A voltage
≥
33 V is selected when the previous output voltage was less than 33 V.
•
Output function is changed between ac or dc voltage when the output voltage is
≥
33 V, ac or dc current, temperature and any other function; resistance and any other
function; capacitance and any other function.
