ORP Verification Mode
To verify ORP separately press ENT for ORP verification. Then
place the probe in the requested solution and press ENT. The
screen will display the message ‘PROBE STABILISING PLEASE
WAIT’. Then rinse the probe in fresh water and place it in the second
solution requested, press ENT when ready. The screen will display
the message ‘PROBE STABILISING PLEASE WAIT’. When this
is completed the user will be prompted to press ENT and will be
returned to the ‘CHOOSE CAL MODE ?’ screen.
Part Number:
AS7250 - 250 mV
Part Number:
AS7475 - 475 mV
Cond/Temp Mode
To calibrate Cond/Temp press ENT for Cond/Temp calibration. Press
the ENT key on the key pad to access the temperature calibration
sub menu.
Steps in Temperature Calibration
Conductivity is calibrated by first setting temperature and this
is important or invalid performance may result. To set the water
temperature sensor, enter the actual temperature (as read from
a thermometer) or accept the temperature value displayed on the
screen. The temperature value is changed via the
↑
(Up) and
↓
(Down) arrows on the key pad. To accept the reading displayed,
press the ENT key on the key pad.
The message screen changes to indicate ‘PLEASE WAIT’. When
the calibration is complete the screen will display ‘TEMPERATURE
CAL OK’ press ENT on the key pad and the conductivity calibration
screen displays.
Steps in Conductivity Calibration
This screen is used to calibrate the conductivity sensor. To
begin, enter the actual conductivity of the solution being used for
calibration. If using tower system water, the value is read from
the independent conductivity meter. Or enter your calibration
solution value into the screen.
When performing a calibration, change the conductivity value via
the
↑
(Up) and
↓
(Down) arrows on the key pad. If required, after
your calibration solution figure is showing on the screen, place the
probe in the solution and press ENT and the screen will display the
message ‘PROBE STABILISING PLEASE WAIT’. Press ENT key
on the key pad when complete and the screen will display ‘COND.
(VALUE) CAL OK’. Press the ENT key a second time and the menu
will return to the ‘CHOOSE CAL MODE ?’ screen.
Note: It is important to clean the conductivity probe before calibrating
conductivity.
