BATTERY INSTALLATION Please install batteries according to the following steps. Please note polarity: "+" (anode) is upward; "-" (cathode) is downward. Note: This salinity meter measures practical salinity converted from electrical conductivity (NaCl Concentration). It does not measure absolute salinity. 2. KEYPAD FUNCTIONS Short press < 2 seconds Long press > 2 seconds 1. Short press to turn on, long press to turn off; 2. When turned off, long press to enter setup; 3. In mode setting, short press to change parameter; 1. When turned on, long press to enter calibration mode. 2. In calibration mode, short press to confirm calibration; 3. In mode setting, short press to confirm parameter selection. Diagram - 1 2 3. COMPLETE KIT Diagram 2 4. CALIBRATION 4.1 Rinse the probe in distilled water and dry it. Short press to turn on the tester. 4.2 Long press to enter calibration mode; Short press to exit. 4.3 Dip the probe into the calibration solution. Stir gently, leave it to stand, LCD displays , short press to complete 1-point calibration. The tester returns to measuring mode, and calibration icon appears at the button left of LCD. 5. SALINITY MEASUREMENT 5.1 Short press to turn on tester. Rinse probe in distilled water and dry it. 5.2 Stir probe in the sample solution gently, leave it to stand. Get readings after the smile icon comes up and stays. 3 6. NOTES 6.1 The tester has self-diagnosis functions: 6.2 The tester has already been calibrated after manufacture. Usually users can use the tester right out of the box or test it in the calibration solution to compare the reading with the standard value. When the error is large, calibrate it before using 7. PARAMETER SETTING 7.1 Parameter setting reference chart: SYMBOL PARAMETER SETTING CONTENT P1 Select salinity unit P2 Restore to factory default CODE Ppt mg/L No - Yes FACTORY DEFAULT ppt No 7.2 How to Setup parameters: When turned off, long press to enter setup short press to switch P1-P2 Short press , parameter flickering short press to choose, short press to confirm parameter selection Long press to switch off. 7.3 Parameter setting notes: a) Select salinity unit(P1): Optional units: ppt mg/L, factory default is ppt. b) Restore to factory default: Select Yes to restore the calibration to the theoretical values and parameter setting to original values. When meter's calibration or measurement performs abnormally, this function can be adopted so the meter goes back to factory default setting and then users can conduct calibration or take measurements again. 4 8.
