5725A Amplifier Output
Boosted voltage operation produces high voltage at higher
current levels than normally available from the Product. During
boosted voltage operation, the potential risk of injury or fatal
accident is greater than during normal operation.
Refer to the 5725A Instruction Manual for setup and installation
instructions.
The 5725A Amplifier boosts ac voltage and both ac and dc current. To set a boosted
output from the 5725A Amplifier:
1.
If not already installed, install the 5725A as described in the 5725A Instruction
Manual.
2.
If the "Boost Amp Types" setting in the Setup Menu has been changed from the
default, select the 5725A for boost operation as described at the beginning of this
chapter.
3.
Make sure the Calibrator and 5725A are in standby (STANDBY annunciator lit).
Push if necessary.
4.
If the UUT is not connected, connect it now as described earlier in this chapter
under "Connect the Calibrator to a UUT." Note that for boosted current, connect to
the 5725A binding posts, and for boosted voltage, connect to the Calibrator binding
posts.
5.
Set the UUT to read the appropriate quantity.
6.
Enter the necessary output value as described under "Setting the Output." Current
entries beyond the standard range of the Calibrator automatically select the
amplifier. Voltage entries in the 220 V-1100 V range automatically select the
amplifier. Note that the 5725A takes over the 1100 V range of the Calibrator.
7.
Boosted voltage output is available at the front panel of the Calibrator. Boosted
current output is available at the front panel of the 5725A Amplifier. When the
5725A binding posts are selected, the Current Output selection indicates the
output location. If the entry has caused a change of output location, must be
pushed to activate the amplifier.
8.
When the range is set to "AUTO", the amplifier is automatically disabled whenever
a current level within the range of the Calibrator is set. Locking the range turns off
this auto disable, so the amplifier can be used at lower current levels.
The 5725A can source a current below 2.2 A to take advantage of the
amplifier higher compliance voltage of the amplifier. To do so, lock onto
the 11 A range when the Calibrator is set for over 2.2 A, or set the lower
current and touch Boost to turn on the amplifier.
9.
To deactivate the amplifier, touch Boost again.
