2. Use the arrow keys to change the parameter, if necessary, and push
.
3. Push and at the same time. The calibration data is shown:
• pH—the slope and offset values are shown alternating with the
deviation (in %) and calibration temperature.
• ORP—the measured mV value and calibration temperature are
shown.
• Conductivity—the cell constant and calibration temperature for each
standard are shown.
Restore the factory calibration
The user calibration can be erased and the factory calibration restored for
pH, ORP and conductivity.
1. Push . The parameter flashes.
2. Use the arrow keys to change the parameter, if necessary.
3. Push and hold until OFF is shown.
The factory calibration for the selected parameter is restored.

Adjust the calibration

The instrument can be adjusted to read a specified solution value for pH,
ORP and conductivity.
1. Rinse the probe. Put the probe in the solution.
2. Push to read the value of the solution.
3. Push . The parameter flashes.
4. Use the arrow keys to select the parameter, if necessary.
5. Push and hold and then push
The measured value flashes.
6. Use the arrow keys to change the value.
7. Push . The display shows OK.

Adjust the temperature

The temperature measurement can be adjusted at 25 °C (77 °F) and/or
85 °C (185 °F) to increase accuracy for pH, ORP and conductivity.

Note: Refer to the probe documentation to find the temperature limits for the probe
that is used.
1. Put the probe and a reference thermometer in a container of water at
approximately 25 °C and allow the temperature to stabilize.
2. Compare the temperature read by the meter with that of the reference
thermometer. The difference is the adjustment value for the meter.
Example: reference thermometer: 24.5 °C; meter: 24.3 °C. Adjustment
value: 0.2 °C.
3. Enter the adjustment value for the 25 °C reading:
a. Push . The parameter flashes.
b. Use the arrow keys to select tEn.
c. Push . 25 °C is shown.
d. Push and then use the arrow keys to enter the adjustment value
for 25 °C. Push . 85 °C is shown.
4. Put the probe and a reference thermometer in a container of water at
approximately 85 °C and allow the temperature to stabilize.
5. Compare the temperature from the meter with that of the reference
thermometer. The difference is the adjustment value for the meter.
6. Push and then use the arrow keys to enter the adjustment value for
the 85 °C reading. Push .

About sample measurements

Each probe has specific preparation steps and procedures for taking
sample measurements. For step-by-step instructions, refer to the
documents that are included with the probe.
Push to take a sample measurement. During measurements, the
parameter flashes and the timer shows the stabilization time. To change
the measurement parameter (if applicable), push and hold
To measure the sample continuously, push
flashes to indicate the continuous measurement mode.
Change the temperature units
The temperature units can be changed when the measurement screen is
shown.
