Checking the Battery
Note
The LOW BAT light flashes red to indicate that the battery needs
replacement.
1. Use the LEAKAGE/CONDUCTIVITY switch to select
CONDUCTIVITY .
2. Press the ON/TEST button to turn on the ULT800.
The self-check routine starts, calibrating the unit. All four LED indicators
flash in sequence, continuing for five cycles. The
READY light glows
amber when the self-test routine completes with a successful battery test.
Checking Solution Conductivity
Note
The LED indicating a test result remains on for 12 seconds. The
ULT800 then powers off to conserve the battery. To resume testing,
power on the ULT800, allow the self-check/battery test to complete,
and then reinitiate the test.
1. Select CONDUCTIVITY .
2. Press the ON/TEST button to perform a measurement cycle.
3. At the end of the measurement cycle (two seconds), the LED
indicates the results of the test.
The green PASS light illuminates if the solution passed the Conductivity
Test. The red FAIL light illuminates if the solution failed the
Conductivity Test. Check that you have immersed the electrodes to a
depth of at least 25 mm (1 inch) and that they are firmly connected to the
ULT800, then retest. If the failure repeats, replace the solution and then
retest.
