14. Press
E
. The calibrator clears your entry from the Control Display and copies it
into the Output Display (below is typical).

15. Press
O
to activate the calibrator output.
A softkey labeled “LO”s appears on the Control Display.

“LO”s (Low Potential Output Terminals) The front panel NORMAL LO and AUX
LO terminals must be tied together either at the UUT or at the Calibrator. When the
front panel NORMAL LO and AUX LO terminals are tied at the UUT, select “open”
with the “LO”s softkey. If the NORMAL LO and AUX LO terminals are not tied at
the UUT, select “tied” with the “LO”s softkey. The default is tied.
How to Set a Dual AC Voltage Output
Note
Tie the terminals NORMAL LO and AUX LO together at the UUT or at the
Calibrator, via the “LO”s softkey selection “tied.”
The calibrator produces a dual ac voltage output by sourcing one ac voltage on the
NORMAL outputs and a second on the AUX terminals.
Complete the following procedure to set a dual ac voltage output. If you make an entry
error, press
G
one or more times to clear the display, then reenter the value.

Caution
Verify the applied voltage to the UUT does not exceed the rating
of the UUT insulation and the interconnecting wiring.
1. Press
R
to clear any output from the Calibrator.
2. Connect the UUT as described earlier in this chapter under “Connecting the
Calibrator to a UUT.”
3. Set the UUT to measure dual ac voltage on the desired range.
4. Press the numeric keys and decimal point key to enter the desired voltage output at
the NORMAL terminals (maximum six numeric keys). For example, 123.456.
5. Press a multiplier key, if necessary. For example, press
c
.
6. Press
V
.
7. The Control Display now shows the amplitude of your voltage entry. For example,
