2.3.1 Power supply connection
To connect the power supply, remove the battery compartment cover located
on the rear panel of the converter unit. Install two AA-type alkaline batteries ob-
serving the polarity marking inside the battery compartment. Replace the battery
compartment cover.
With a power supply installed in the battery compartment, the analyzer
can indicate time, when turned off. The dot between hours and minutes flick-
ers at an interval of 1 s.
Time indication may be switched off and on again by pressing the
MODE
button, with the analyzer off.
Proceed as follows to correct time:
press the
CAL
button, minutes will start blinking on the display;
use the
MODE
and
ENTER
buttons to set the minute value;
press the
CAL
button, hours will start blinking on the display;
use the
MODE
and
ENTER
buttons to set the hour value;
press the
CAL
button to complete time setting, the analyzer goes into the
time indication mode.
Switch on the analyzer and check if the display shows DOC or temperature
readings in mg/dm
3
or % sat., or °С respectively.
WARNING: ALWAYS OBSERVE polarity when installing batteries. Fail-
ure to meet this condition may damage the analyzer!
When the display shows the
sign, replace AA-type alkaline batteries.
2.3.2 Oxygen sensor setting-up procedures
Since the oxygen sensor from the analyzer set is delivered in the “dry” state,
it should be filled with electrolyte included with the delivery set, as described in pa-
ra.2.6.3, and submerged in distilled water for a minimum of 8 h.
Make sure two AA-type alkaline batteries are installed in the converter unit.
Regardless of whether the analyzer is on or off, the sensor will receive polarizing
voltage needed to build up an electrode system.
