Introduction
This chapter explains the main (primary) inputs and outputs of the Product. Connection
figures are also shown so that you properly connect the Product to a unit under test
(UUT).
DC Voltage Output
The Product can source dc voltages from 0 V to 100 V and uses these four ranges for
maximum accuracy:
• 0.1 V
• 1 V
• 10 V
• 100 V
For dc voltage output:
1. Disconnect test leads from external devices.
2.
Push

to select dc voltage and current mode, if not already selected.
3. If dc current mode is shown, push the key again to go to dc voltage mode.
4. Connect the UUT to the voltage output terminals of the Product as shown in Figure
2-1.

5. Use the numeric keypad to type the necessary output value and push E.
6. As an alternative, use M or  to select a digit to change, followed by  or P to ramp
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.
7. When dc voltage mode is first selected, the Product is put into standby (Stby) mode
which puts the positive (+) output jack into a high-impedance condition (>100 ke)
for safety. To put the output into the active condition, push  to toggle between the
standby and operate modes.
8. The standby mode is also started in these situations:
• If a fault occurs during operation, such as an overload or short circuit condition.
• As a safety feature for all new outputs larger than 30 V dc. Refer to the product
specification section of this manual for maximum drive currents.
