7.2.3 Reference measurement (Ref Meas)
A reference measurement enables you to assign the voltage
value 0 mV to the calibration curve of your electrode for a
specific ion concentration (reference concentration).
Prerequisite:
l The measured value display must show the voltage.
l A valid calibration must be available.
1 Switch to the Display mode.
2 Only if no valid calibration is available
(no sensor symbol on the measured value display):
Perform a calibration (see section 7.3).
3 Switch to the display of the voltage (U) with m.
4 Switch to the Menu mode.
5 Use 46 to select the main Meas menu.
6 Select the ISE menu item with
82.
7 Confirm the ISE menu item with g.
8 Select the ISE setup menu item with
82.
9 Confirm the ISE setup menu item with g.
10 Select the Ref Mess menu item with
82.
11 Confirm the Ref Meas menu item with g.
The Ref Mess function is active (✔).
The
- symbol flashes on the measured value
display.
12 Switch to the measured value display with
m.
13 Open the input field for temperature and reference
concentration with
