The following screen will appear if Grab Cal is successful.
The screen will return to the Turbidity Cal Menu.
7.10.4 Grab Calibration - Turbidity
If desired, the turbidity sensor can be calibrated
against the turbidity reading from another instrument.
The analyzer treats the value entered by the user as
though it were the true turbidity of the sample.
Therefore, grab sample calibration changes the sensi-
tivity, it does not apply an offset to the reading.
This screen appears after selecting
Grab calibration.
To calibrate Pulse Flow:
1. Press the
MENU
button
2. Select
Calibrate.
Press ENTER.
3. Select
Sensor 1
or
Sensor 2
corresponding to
Flow. Press ENTER.
4. Select
Pulse Flow.
Press ENTER.
The following screen will appear.
A detailed flow diagram is provided at the end of Sec. 7 to guide you through the calibration routines.
7.11 Pulse Flow
7.11.1 Description
A variety of pulse flow sensors can be wired to the Flow signal input board to measure flow volume, total volume
and flow difference (if 2 Flow signal boards are installed). The Model 1056 Flow signal board will support flow
sensors that are self-driven (powered by the rotation of the impeller paddle-wheel).
THIS SECTION DESCRIBES HOW TO CALIBRATE THE MODEL 1056 WITH AN ATTACHED FLOW SENSOR.
THE FOLLOWING CALIBRATION ROUTINES ARE COVERED.
