Next, use the up or down arrow keys to adjust the shut off time from 0
to 60 minutes. Press enter to save the new shutoff time. Next, highlight
the ESC-Exit box and press enter to close the submenu.
To disable Auto Shutoff, set the Time in Minutes to 0 (zero).
cell constant
The Cell Constant displays the cell constant of the conductivity cell.
The cell constant is calculated and updated each time a conductivity
calibration is performed. The cell constant range is 4.0 to 6.0. Resetting
the System Menu resets the cell constant to 5.0.

To reset the Pro1030 settings and conductivity cell constant back to
factory default, press the down arrow key while in the System Setup
menu until the Reset - box is highlighted, then press enter. The
instrument will prompt you to confirm the reset. Highlight Yes and
press enter to continue with the reset or highlight No and press enter
to cancel the reset. A Factory Reset will not affect data saved in the
instrument’s memory.

All Pro1030 cables have built-in temperature sensors. Temperature
calibration is not required nor is it available.
ph calIBratIon
The Pro1030 pH sensor can be calibrated by performing a 1, 2 or 3-point
calibration. At least one of the calibration points must be done with
pH buffer 7 or 6.86. For auto buffer recognition to work properly with
an older or dirty sensor, calibrate in buffer 7 or 6.86 first. For highest
accuracy, use fresh, traceable pH buffers and ensure the sensor and
calibration vessel are clean.
1-PoINT CALIBRATIoN
1. Place the sensor in pH buffer 7 or 6.86 and allow the temperature
and pH readings to stabilize.
2. Press and hold Cal for three seconds.
3. Highlight pH and press enter. If pH is not listed as an option,
check the System Setup menu to ensure pH is enabled in the
ISE Sensor Type menu.
4. Highlight 1 point and press enter.
5. If necessary, use the up and down arrow keys to adjust the pH
buffer value. Note the pH mV reading which ideally should be
between -50 and +50 in buffer 7.
6. Press enter to complete the calibration or press Cal to cancel.
