Operation

4.6 Calibration

4.6.1 Temperature Sensor Calibration

The probe contains a temperature sensor which is factory pre-set. If there are setting 
questions, the data can be validated using a high precision thermometer using 

Table 1

 

and performing the steps in 

section 4.6.1.1 on page 22

.

DISP PH FORMAT (9184sc T.F.C or 9184sc Ch Acid only)

Choose either XX.XX pH or XX.X pH.

pH MAXIMUM  (9184sc T.F.C only)

Allows user to set the maximum pH allowed value. An higher value will display a PH TOO HIGH error message.

LOG SETUP

Allows user to select data logging interval for the sensor and temperature. 

FILTER

Adjust for + s. This averages the signal over the specified time interval.

MAINS FREQ

Choose 50 or 60 Hz.

CONFIGURE (continued)

DEFAULT SETUP

Resets the sensor configuration to default settings. 

DIAG/TEST

PROBE INFO

Displays the driver and software versions and the serial number. 

CAL DATA

Displays OFFSET: °C, SLOPE: in A/mg and OFFSET: uA, SLOPE: %

SIGNALS

Displays INT, TEMP RAW, MV RAW and PH RAW.

COUNTERS

Displays sensor total time and humidity suppressor.
