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.Conductivity Calibration 4.1 Press key to switch to conductivity measurement mode. Rinse the probe in distilled water and dry it. 4.2 Pour certain amount (about half volume of the calibration bottle) of 1413μS/cm and 12.88 mS/cm conductivity calibration solution into accordant calibration bottles.
5. 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. Get readings after comes up and stays.
5.4 TDS and conductivity is linear related, and its conversion factor is 0.40-1.00. Adjust the factor in parameter setting P5 based on the requirements in different industries. 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.
6.3 Parameter Setting Instruction a) Automatic lock (P1): Select “On” to activate auto lock function. When reading is stable for more than 10 seconds, the tester will lock the value automatically, and HOLD icon will display on LCD. Press key to cancel auto hold. b) Backlight (P2) “Off”-turn off backlight, “On”-turn on backlight, 1- backlight will last for 1 minute.
