User manual EUTECH INSTRUMENTS PTTESTR 35

[. . . ] to begin pH Salinity (SALt) Option (PCS Testr only) Choose PPt (parts per thousand) or Per (percentage %) as unit of measure. Total Dissolved Solids (tDS) Option (PT and PCS Tester only) FACt factor the instrument uses to convert from conductivity to TDS value. Adjustable from 0. 40 to 1. 00 (default factor is 0. 71). Getting Started: Your instrument has been factory calibrated and usually works well out of the box. However, after extended periods of non-use, it's best to remove the sensor cap and soak the sensor (pictured here) in warm tap water or pH buffer for 10 minutes or so. A brief rinse with deionized (DI) water is OK, but avoid soaking or storing in deionized water as this will shorten the pH electrode life. [. . . ] 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. 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. 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. Conductivity Range 0. 0 ­ 200. 0 µS 201 ­ 2000 µS 2. 01 ­ 20. 00 mS 1. 2. Automatic Calibration Value 84 µS 1413 µS 12. 88 mS Available with PCS only PC or PCS PC or PCS to turn meter on and to select conductivity mode as needed. The primary display will show the un-calibrated value, while the press secondary display display should search for and lock on the closest automatic calibration value. 3. 4. to confirm the calibration Allow the primary display to stabilize, then press value. The primary value will blink briefly before returning to measurement mode. [. . . ] When applying for authorization, please include information regarding the reason the item(s) are to be returned.
