Figure 3-6. Voltage Operate Mode

Warning

Both the 5700A and 5725A can produce fatal voltages. boosted voltage operation produces high voltage at higher current levels than normally available from the 5700A. during voltage operation, the potential risk of injury or fatal accident is greater than during normal operation.

Voltage operate mode is when only the VOLTAGE MODE indicator is lit. In voltage operate mode, amplified voltage output is available at the 5700A binding posts. Voltage operate occurs if "5725A" is selected in a 5700A setup menu as the voltage amplifier, and the next two conditions are true:

An ac voltage 220V or above is showing on the 5700A Output Display with the OPERATE annunciator lit.

The BOOST indicator on the 5700A is lit.

Note

If condition 1 is true, the BOOST indicator can be toggled on and off by pressing the 5700A BOOST key. If the BOOST indicator is off, then the 5725A is in standby mode.

Note

Under certain settings of ac voltage, especially high voltage between 1 to 5 kHz, a whine from the 5725A is audible. This originates from the output transformer, and is normal.
