6.6.3 ORP calibration (Redox)
1 Press
the
symbol.
2 Press
the
Calibration menu.
3 Select the “ORP” measurement menu.
4 Press the parameter “Cal. value”.
5 Place the beaker into the bottom clip and
fill it with calibration solution "478 mV" or
clamp a bag with calibration solution "478
mV" into the bottom clip.
6 Close the sample water inlet and sample
water outlet and briefly open the sample
extraction unit (drain) to release the pres-
sure. Close the sample extraction unit
(drain) again.
7 Screw the ORP sensor into the cell body
cover.
8 Dip the ORP sensor through the top clip at
least 2 cm deep into the calibration solu-
tion and move it slightly until the indica-
ted pH value remains constant.
9 Press the “Calibration” button. An input
field opens.
10 Use the keypad to enter the value to be
calibrated.
11 Press "Enter" to save the entry.
12 Remove the ORP sensor from the top clip.
13 Screw the ORP sensor into the cover of
the cell body of the flow cell.
14 Open the sample water inlet and outlet
again.
This concludes the ORP calibration.
6.6.4 Conductivity calibration
1 Press the
symbol
2 Tap
the
menu.
3 Select the “Conductivity” measurement
menu.
4 Tap the parameter “Calibration.”
5 Place the beaker into the bottom clip and
fill it with calibration solution.
6 Close the sample water inlet and sample
water outlet and briefly open the sample
extraction unit (drain) to release the pres-
sure. Close the sample extraction unit
(drain) again.
7 Release the clamp connection of the con-
ductivity sensor and remove the conducti-
vity sensor from the cell body cover.
8 Dip the conductivity sensor into the cali-
bration solution through the top clip and
move it slightly until the indicated pH
value remains constant.
9 Press the “Calibration” button. An input
field opens.
10 Use the keypad to enter the value to be
calibrate.
NOTICE
ORP (Redox) sensors have long running-in
times. This means that after calibration with
calibration solution, it can take several
hours for the measured value to stabilize.
NOTICE
•
Conductivity sensors have no running-in
time.
•
When calibrating with calibration solu-
tion, it must be noted that it takes seve-
ral minutes for the temperature
measurement of the conductivity sensor
to become stable.
•
Depending on the area of application,
use appropriate calibration solution:
Calibration solution 600 µS/cm:
con-
ductivity measurement in µS/cm
Calibration solution 60 mS/cm:
conduc-
tivity measurement in mS/cm
•
Furthermore, a measuring range must
be set before calibration, which is suita-
ble for calibration solution used:
Calibration solution 600 µS/cm:
select
measuring range 1000 µS/cm or 2500
µS/cm.
Calibration solution 60 mS/cm:
select
measuring range 100 mS/cmor higher.
•
Alter calibration, the orignal measuring
range can be adjusted again.
