Temperature calibration is always recommended upon sensor replacement. It may also be desirable to adjust the temperature to match a certified accurate thermometer or another Testr. The temperature value is common to all parameters so only one calibration is needed. [. . . ] Press or to choose (Parameter) will appear. (System Setup) (Parameter Setup) or to enter the selected setup menu. *IMPORTANT* It is necessary to save your Parameter and System changes in order for them to take effect. 1. When you are finished making your desired changes, press both and time and keep them pressed until you see "SA" (Save) on the display. Use Single-Point Calibration to apply a single calibration value across all ranges. Use Multi-Point Calibration for individual calibration in each range. This will restrict an individual calibration so that it is applied to one range only. When using multi-point calibration, perform a calibration in each range that you expect to use for best results. TIP: The PC Testr 35 and PCS Testr 35 are capable of single or multi-point conductivity SPC (Single-Point Calibration) Choose YES or NO (multi-point calibration). System Setup: Select to make changes relating to the system. Note: other than changing Temperature units, it is advised to keep the factory default settings for best results. To Navigate the System menus: Press to select or confirm the displayed option. 4. With the primary display "SA" and secondary display "YES", press to save the changes. The instrument will resume measurement mode with new setting(s). Conductivity Calibration (Automatic): For best results, calibrate with certified accurate conductivity calibration standards. Selection of multi-point calibration will allow up to three of the following values, while Single-point calibration will allow only one; choose 84 S, 1413 S, or 12. 88 mS. Sensor Replacement: Your instrument includes a replaceable sensor (Eutech PCSENSOR - 01X097108 / Oakton 35425-50). If the tip gets damaged or as the sensor wears over time, the entire sensor can easily be replaced. To remove the old sensor, simply twist off the ribbed collar and pull the sensor straight out. Message >75% battery life remaining Indicates 50-75% battery life remaining 25-50% battery life remaining No bars & blinking = replace batteries Err Unstable pH reading / Slow response "Ur" (Under range) or "Or" (Over range) Meter not responsive Secondary display continually scrolls Calibration error, usually attempting to calibrate to a value which is out of range or under range. Clean, rehydrate, and replace if necessary. Could also be due to low battery condition or sample with temperature that has not stabilized. Most often caused by dry electrode that needs to be re-hydrated / soaked. Sensor may not be completely submersed or is not connected to Testr body properly. If "Hold" on display, press Hold key to resume live measurement. The automatic calibration standard is not within expected calibration range. Use fresh standard or an alternate calibration standard.

Press or standard. to manually adjust the primary display to your calibration Press to confirm the new adjusted value. The primary value will blink briefly before returning to measurement mode. Repeat steps 2 & 3 with additional calibration standards if desired. Hold Function: For prolonged observation of a reading, press during measurement mode to freeze the display. [. . . ]
