Notes
Scrolling the output when the output value is already larger than 30 V will
not place the Calibrator in standby mode for each new value.
Automatic setpoints higher than 30 V will not put the Calibrator in standby
mode for each new value.
9. The Product can be locked to a specified voltage range. Select a value in that range
and then push and + to select the secondary RNG LOCK function.
DC Current Output
The Product can source dc current from 0 mA to 100 mA.
1. Disconnect test leads from external devices.
2.
Push
to select dc voltage and current mode, if not already selected.
3. If dc voltage mode is shown, push the key again to go to dc current mode.
4. Connect the UUT to the current output terminals of the Product as shown in
Figure 2-2.

5. Use the numeric keypad to type the necessary output value and push E.
As an alternative, use M or cursor key to select a digit to change, followed by or
P to move the digit up or down. This method gives you a simple solution when
small changes to an output value are necessary, or if is necessary to increment or
decrement decades.
6. When dc current mode is first selected, the Product is put into standby (Stby) mode
which puts the positive (+) output jack into a high impedance condition (>100 k e)
for safety. To put the output into the active condition, push to toggle between the
standby and operate modes.
The standby mode also operates in these situations:
• No connection made to the output terminals.
• The voltage compliance is larger than a given output current. The Product has a
typical-voltage compliance of 10 V. This is so that the 4 mA-20 mA application loads
to a maximum of 500 Ω can be driven. At maximum current of 100 mA, the
maximum load is 100 Ω.
