The BATTERY VOLTAGE diagnostic displays no-load DC voltage
supplied by the internal battery. When this test is started, the
sampler will briefly display the battery voltage.
To display the no-load battery voltage:
1. Select the BATTERY VOLTAGE option and press Enter.
2. The display briefly shows the voltage.
If the voltage is below 2.2 VDC, the internal battery should be
replaced. Contact your authorized Isco service facility or the
Teledyne Isco factory for assistance.
Note
Should there be a loss of AC power and the internal battery's
no-load voltage is below 2.2 VDC, the sampler might lose data
and settings from its memory. It is recommended that you
retrieve the data and record the program and configuration
settings in case of memory loss.
The LOADED BATTERY VOLTS diagnostic displays the loaded DC
voltage supplied by the Main CPU board's internal battery. A
loaded test provides a better indication of battery performance.
When this test is started, the sampler will display the voltage
with a 20K load at one second intervals. The test continues for
15 seconds or until you press the Enter button to abort the test.
Note
Repeated use of the Loaded Battery Volts diagnostic will
shorten the battery life.
To display the loaded battery voltage:
1. Select the LOADED BATTERY VOLTS option and press
Enter.
2. The display shows the voltage at 1 second intervals for 15
seconds. You can abort the test by pressing the Enter
button.
If the voltage is below 2.2 VDC, the internal battery should be
replaced. Contact your authorized Isco service facility or the
Teledyne Isco factory for assistance.
Note
Should there be a loss of AC power and the internal battery's
loaded voltage is below 2.2 VDC, the sampler might lose data
and settings from its memory. It is recommended that you
retrieve the data and record the program and configuration
settings in case of memory loss.
