[. . . ] If you intend to calibrate with one or more standards that are not listed in TABLE 1, the CON 700 must be set for manual calibration instead. 4 The factory default is automatic conductivity calibration. See Section 6. 10 to change this setting. There is no automatic calibration value available for conductivity range 1.

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. 5 The factory default is Single-Point Calibration. See Section 6. 11 to change this setting. 4. 3 General Calibration Tips For best results, periodic calibration with known accurate standards is recommended. A maximum of one calibration point per range can be performed. If multiple calibration points are used in the same range, the most recent one will replace the previous one. When the electrode is replaced, it is best to clear the calibration to the factory default values (see Section 6. 13). Rinse or immerse the probe before calibration and between samples with clean water (deionized water is ideal). The CON 700 has non-volatile memory which will retain all calibration values, as well as meter settings and memory values upon meter shut down or unexpected power loss. To protect from erroneous calibrations, the allowable tolerance is ±40% of the factory default value. Low conductivity standard solutions (less than 20 µS) are unstable and are very temperature dependent. As a result, reproducible calibration results are challenging in lowest measurement range #1 (0. 00 to 20. 0 µS). 4. 4 Automatic Conductivity Calibration Procedure 1) 2) 3) Press as needed to select conductivity (S or mS). Dip the electrode into the conductivity standard and press . The primary display will show the factory default value, while the secondary display will lock on the appropriate automatic standard value from TABLE 1. When the READY indicator appears, press to accept. The primary reading will flash briefly before returning to measurement mode upon successful calibration. 4) 6 4. 5 Manual Conductivity & TDS Calibration Procedure 1) 2) 3) as needed to select conductivity (S or mS) or TDS Press (ppm or ppt) calibration. Dip the electrode into the calibration standard and press Provide stirring for best results. The primary display will show the current reading, while the secondary display will be the factory default value. [. . . ] Ideally T1 and T2 should bracket your measurement temperature, and should not differ by more than 5 ºC. Calculate the temperature coefficient of your solution according to the formula shown above. Enter the calculated temperature coefficient into the meter. The calculated temperature coefficient will now be applied to all the meter readings. 14 9.
