1. Battery Installation Please install batteries according to the following steps. Please note direction of batteries: All POSITIVE SIDES (“+”) FACING UP. (Wrong installation of batteries will cause damage to the tester and potential hazards) ① Pull the battery cap up ②...
3.Complete Kit Diagram - 2 4.Preparation Before Use If it is first-time use or the tester hasn’t been used for over 30 days, pour a little 3M KCl storage solution in the probe cap (about a fifth of the probe cap), and soak the probe for about 5 to 15 minutes.
5.pH Calibration 5.1 Rinse the probe in pure water and dry it. 5.2 Pour certain amount (about half volume of the calibration bottle) of pH 7.00 and pH 4.00 buffer solution in separate calibration bottles; 5.3 Long press to enter calibration mode; Short press to exit.
b) For pH Calibration buffer solutions, we recommend that users replace new buffer solution after 10 to 15 times of use to keep the standard buffer’s accuracy. Do NOT pour the used calibration solutions back into the solution bottles in case of contamination. c) pH probes will NOT give accurate and stable readings in distilled or deionized water.
calibration. If it is inaccurate, follow the steps in 7.1 to 7.4 to complete the 2 point of calibration using 12.88 mS buffer solution. 8.Conductivity Measurement Press key to turn on the tester. Rinse the probe in distilled water and dry it. Dip the probe in sample solution, stir gently, and allow it to stand still in the solution until a stable reading is reached.
e) TDS and conductivity is linear related, and its conversion factor is 0.40-1.00. Adjust the factor in parameter setting P5. The factory default setting is 0.71. Salinity and conductivity is linear related, and its conversion factor is 0.5. The tester only needs to be calibrated in Conductivity mode, then after calibration of conductivity, the meter can switch from conductivity to TDS or salinity.
9.3 Parameter Setting Instruction a) Select standard pH buffer solution (P1): There are two options of standard buffer solutions: USA series and NIST series. Refer to following chart: pH Standard Buffer Solution Series Icons USA series NIST series 1.68 pH and 4.00 pH 1.68 pH and 4.01 pH Three-point 7.00 pH...
Screw off the probe ring, unplug the probe, plug in the new replacement probe (pay attention to the probe’s position), and screw on the probe ring. The model numbers of replacement probes that are compatible with PC60 are: PC60-E ...
