Conditioning the Analyser
WARNING: FAILURE TO DISCONNECT POWER TO THE Cl1000 RESIDUAL ANALYSER
PRIOR TO ACCESSING THE INTERIOR OF THE ELECTRONICS ENCLOSURE MAY RESULT
IN SERIOUS PERSONAL HAZARD FROM EXPOSURE TO LETHAL VOLTAGES.
3.1.1
Remove the soaker teat from the measuring end of the electrode and place the reference
electrode in the reference electrode reservoir (See Figure 2).
Note: Retain the soaker teat for future use.
CAUTION: REFERENCE ELECTRODE MUST REMAIN IN REFERENCE ELECTRODE
RESERVOIR AT ALL TIMES DURING THE OPERATION OF THE Cl1000. REMOVAL
OF THE REFERENCE ELECTRODE FROM THE RESERVOIR DURING OPERATION
MAY CAUSE ERRONEOUS READING AND LEAD TO EQUIPMENT DAMAGE.
3.1.2
Start the sample water flow at approximately 150 ml/minute. If using the data from the
built in flow cell make sure the flow rate displayed in the diagnostics screens is at least
500mls/minute (the flow cell is used to detect flow/no flow and the actual flow rate
displayed tends to under read the actual real flow rate.
Water must be flowing over the overflow weir in the sample inlet chamber to drain.
3.1.3
If the system requires occasional cutoff, provisions must be made to keep the electrodes
wet.
3.1.4
Sampling from a pressurized source may require a pressure reducing valve to hold the
flow constant. Maximum desired pressure is 10 psig (0.6 bar).
3.1.5
If sampling from turbid water, a flushing Y-strainer is necessary to prevent clogging of the
sample line. Other types of filters are not recommended.
3.1.6
Connect power to the analyser terminals. (See Section 2.4)
3.1.7
Switch on the power to the analyser at the isolation point.
3.1.8
Turn ON the power switch on the analyser. To clear the analyser memory and return the
set up parameters to their factory defaults (perform a cold start), hold down the two left
keys on the keypad while you turn the analyser power switch ON.
NOTE:
The analyser will take approximately 45 seconds to ‘boot up’.
3.1.9
Go to the analyser ‘Set Up’ to adjust any of the preconfigured screen settings on the
monitor. See Section 3.3.
3.1.10
For maximum accuracy the analyser requires a stabilisation time of up to 24 hours
however a result within
±
10% is normally achieved within 1 hour. The analyser should be
run continuously, without interruption of power. Turning off the cell, even momentarily, will
require the appropriate stabilisation time upon restart. During operation, sample must be
feeding into the cell.
3.1.11
After stabilisation, calibration of the analyser may begin. See Section 3.4.
3.2 Programming the Monitor
All programmable options necessary for operation of the monitor are accessible through the four-
button keypad and display. To move from screen to screen, follow the instructions on the display.
From anywhere in the software, the

key (far right key) will always return the monitor to the
