Front-Panel Operation
Set the Output 4
4-23
The Current Output item selects one of three locations for non-boosted (current sourced
by the Calibrator, for example) current output:
• OUTPUT binding post (NORMAL, which is the OUTPUT HI binding post, also the
default setting)
• AUX, which is the AUX CURRENT OUTPUT binding post
• Boost which is the 5725A Amplifier binding posts. (The 5725A must be turned on,
but not necessarily activated.)
Non-boosted current from the Calibrator is not available at the 52120A amplifier binding
posts.
Resistance Output
In the resistance function, the Calibrator supplies a choice of 18 standard resistance
values or a short at the output terminals. The values available are:
0 Ω
1.0 Ω
1.9 Ω
10 Ω
19 Ω
100 Ω
190 Ω
1.0 kΩ
1.9 kΩ
10 kΩ
19 kΩ
100 kΩ
190 kΩ
1.0 MΩ
1.9 MΩ
10 MΩ
19 MΩ
100 MΩ
To select a resistance output:
1. Make sure the Calibrator is in standby (STANDBY annunciator lit). Push if
necessary.
2. If the UUT is not connected, connect it now as described previously in this chapter
under “Connect the Calibrator to a UUT.”
3. Set the UUT to read resistance on the appropriate range.
4. Push the numeric keys of the nominal resistance, or touch “Ω Value Table” to show a
list of the selectable resistance values as shown below.
