Note

 

 

 

An overcompliance fault occurs if a low-resistance load is not connected to the enabled 5725A binding posts when entering current operate mode.

Current operate mode is when only the CURRENT MODE indicator is lit. In current operate mode, current output (either 5725A amplified current or redirected 5700A current) is available at the 5725A binding posts. Current operate occurs under the following conditions:

When, on the 5700A, the current output location is set to "5725A", and any ac or dc current level is showing on the 5700A Output Display with the OPERATE annunciator lit.

If "5725A" is selected in a 5700A setup menu as the current amplifier, and any of the following conditions are true:

1.An ac or dc current 2.2A or above is showing on the 5700A Output Display with the OPERATE annunciator lit.

2.Any level of dc current is showing on the 5700A Output Display with the OPERATE annunciator lit, and the BOOST key on the 5700A is pressed so that the BOOST indicator is lit.

3.An ac current 1A or above is showing on the 5700A Output Display with the OPERATE annunciator lit, and the BOOST key on the 5700A is pressed so that the BOOST indicator is lit.

4.The 5700A is ranged locked on the 11A range, and any dc current or an ac current 1A or above is showing on the Output Display with the OPERATE annunciator lit.

Note

Under certain settings of ac current, especially high current at frequencies above 1 kHz, a whine from the 5725A is audible. This is caused by a piezo effect in the current output transistors, and is normal.
