5.2 Calibration Reminder
The tester will automatically remind you when recalibration is due, ensuring consistent accuracy.
6. Antretyen
6.1 Netwaye Capteur a
After each use, rinse the sensor thoroughly with distilled or deionized water to prevent residue buildup. Do not scrub the sensor vigorously.
6.2 Depo
Always replace the protective cap after use. For long-term storage, ensure the sensor is kept moist. Refer to the product packaging or Apera Instruments website for specific storage solution recommendations if applicable.
6.3 Ranplase Capteur a
The titanium EC sensor is replaceable. If the sensor performance degrades significantly or it becomes damaged, a new sensor can be purchased and easily installed by twisting off the old one and attaching the new one.
NAN. Depanaj
| Pwoblèm | Kòz posib | Solisyon |
|---|---|---|
| Lekti kòrèk | Sensor is dirty or dry; Calibration is outdated or incorrect; Damaged sensor. | Clean the sensor; Recalibrate the tester; Replace the sensor if damaged. |
| Tester does not power on | Pil mouri; Pil yo pa byen enstale. | Ranplase pil yo; Tcheke polarite pil yo. |
| "CAL Er" error during calibration | Incorrect calibration solution; Contaminated solution; Sensor issue. | Ensure correct 2.77 EC solution is used; Use fresh calibration solution; Clean or replace sensor. |
