Calibration

CAUTION

Chemical exposure hazard. Obey laboratory safety procedures and wear all of the personal protective equipment appropriate to the chemicals that are handled. Refer to the current safety data sheets (MSDS/SDS) for safety protocols.

Calibrate the tester before initial use and when:

• Results drift
• Results are not accurate
• “?” shows next to the calibration icon

Calibrate the tester with the:

• Auto calibration procedure
• Custom calibration procedure5

Before the initial calibration and after a dry storage, soak the sensor for several minutes in the sample or tap water.

Auto calibration

Items to collect: One, two or three auto-recognition calibration standards

1. Set the power to on.

2. Remove the cap from the sensor.

3. Push to go to calibration mode.
   The auto-recognition standard(s) to measure shows on the bottom line.

• Stabilization is slow
• Results drift or are not accurate
• Calibration failure occurs

1. Soak the sensor in the applicable cleaning agent. Refer to Table 3.
2. Rinse or soak the sensor in demonized water for 1 minute.

Table 3 Cleaning agents

Replace the batteries
When the battery icon flashes or the tester will not come on, replace all four batteries. Refer to Install the batteries on page 5.

Replace the sensor
Note: Only Pocket Pro+ testers have replaceable sensors.
To replace the sensor, refer to the instructions supplied with the sensor.

Troubleshooting

Clean the sensor on page 9.
ECAL| Calibration failure. The pH calibration slope is greater than ±15%.| Gently clean the sensor. Refer to Clean the sensoron page 9. Calibrate again. If calibration failure continues, replace the tester or sensor as applicable.
“- – – -“(top line)| The parameter value is not within the measurement range of the tester. Refer to Specifications on page 2.| Make sure that the value of the sample is within the measurement range of the tester. Gently clean the sensor. Refer to Clean the sensor on page 9. Calibrate as necessary.
“- – – -“(bottom line)| The temperature value is not within the operating temperature range of the tester or a temperature sensor failure occurred. Refer to Specifications on page 2 for the operating temperature range.| Make sure that the sample temperature is within the operating temperature range of the tester. Contact technical support as necessary. Note: The tester can still be used if a temperature sensor failure has occurred, but without automatic temperature compensation.
Battery icon flashes| The batteries have less than 10% power remaining.| Replace all four batteries. Refer to Install the batteries on page 5.
