4.2.3 Display Measurement Data
Measurements can be called up as follows:
1. For voltage, the left display always displays the measured output voltage unless the
knob is turned. As the knob is turned, the programmed voltage will be displayed
instead. After releasing the knob for about 3 seconds, the display reverts back to the
measured voltage.
2. All other measurements can be displayed by using the SELECT button to toggle
through the available measurements. The LED’s above the LCD indicate the current
selection. The knob only affects programmed frequency and current limit.
3. Moving the right shuttle knob will interrupt the select measurement and put the
display back in Current Limit adjust mode.
Note: For peak current, power and power factor measurements, Option -OP1 is required.
4.2.4 Change the Voltage
The voltage range can be changed as follows (If the 2001RP-AV is configured for a single
voltage range, this does not apply):
1. Press the RANGE button located in the upper left corner. The output voltage will
reset to 0 volts.
2. Use the left shuttle knob to set the output voltage.
The AUTO voltage range can be selected as follows:
3. Press the RANGE button located in the upper left corner. The AUTO LED will
illuminate. The AC source is now in Auto range mode. Turn the left shuttle knob to a
value above 150 V. The unit will switch to high range and the HIGH LED will
illuminate.
4. Turn the left shuttle knob to reduce the voltage to a value below 150 V. The AC
source will switch to the low voltage range and the HIGH LED will turn off.
To turn off the AUTO voltage range, proceed as follows:
5. Press the RANGE button. This puts the AC source back in normal mode. The
voltage range that was in effect does not change. The AUTO LED will turn off.
6. Press the RANGE button again to toggle voltage ranges.
