ATTENTION

1. You may find a few drops of water in the probe cap. These water droplets are added to maintain the sensitivity of the conductivity sensor before the product leaves  factory. It does NOT mean the product is used.
2. The batteries are already preinstalled. Just pull off the paper slip before using the tester. When you replace the batteries, make sure to follow the correct directions: all  four AAA batteries’ positive sides must FACE UP.

Complete Kit

Things to Know Before Use

A few drops of destilliertes water are added to the probe cap to keep the conductivity electrode in an activated state before the tester leaves factory. Generally, users can start  using the tester directly. For conductivity electrode that hasn’t been used for a long time, users should soak the electrode in 12.88 mS calibration solution for 5-10 minutes or  in tap water for 1 to 2 hours before use. Rinse the electrode in distlled/deionized water after each measurement.
The sensing rod of Model conductivity electrode is coated with platinum black to minimize electrode polarization and expand measuring range. The platinum black coating  adopted our special processing technology, which improves the electrode performance and the firmness of the coating. If the black sensing rods are stained, gently clean the  electrode with a soft brush in warm water containing detergent or alcohol.
Things needed in addition to what’s in the box:
a. Distilled or deionized water (8-16oz) for rinsing the probe after each test
b. Tissue paper for drying the probe

Conductivity Calibration

How to calibrate

1. Press ****key to switch to conductivity measurement mode (Cond). Rinse the probe in distilled water and dry it.
2. Pour certain amount of 1413μS/cm and 12.88mS/cm conductivity calibration solution into corresponding calibration bottles (to about half volume of the bottle).
3. Long press key to enter calibration mode, short press to go back to measurement mode.
4. Place the probe into 1413 μS/cm conductivity calibration solution, shake it for a few seconds and allow it to stand still in the solution until a stable reading is reached. When stays on the LCD screen, short press key to complete 1 st calibration, the tester returns to measurement mode and indication icon will appear at the bottom  left of the LCD screen.
5. After calibration, place the probe in 12.88 mS/cm conductivity calibration solution. If the value is accurate, it is not necessary to conduct 2 nd point calibration. If it is  inaccurate, follow the steps in 3) to 4) to complete the 2 nd point of calibration using 12.88 mS/cm calibration solution.

Notes

1. TDS, salinity, and resistivity values are converted from conductivity. So only conductivity needs to be calibrated.
2. The tester can calibrate 1413 μS/cm, 12.88 mS/cm, and 84 μS/cm(sold separately) conductivity calibration solution. User can conduct 1 to 3 points calibration. Refer to  the table below. Usually calibrating the tester with 1413 μS/cm conductivity buffer solution alone shall meet the testing requirement.
   Calibration Indication Icon| Calibration Standards| Measuring Range
   ---|---|---
   | 84 μS/cm| 0 – 199 μS/cm
   | 1413 μS/cm| 200 – 1999 μS/cm
   ****| 12.88 mS/cm| 2.0 – 20.00 mS/cm
3. The tester has been calibrated before leaving factory. Generally, users can use the tester directly or users can test conductivity calibration solutions first. If the error is large, then calibration is needed.
4. Conductivity calibration solutions are easier to get polluted than pH buffers, we recommend that users replace new conductivity solutions after 5 to 10 times of use to keep the standard solution’s accuracy. Do NOT pour the used calibration solutions back into the solution bottles in case of contamination.
5. Temperature compensation factor: The default setting of the temperature compensation factor is 2.0%/ ℃. User can adjust the factor based on test solution and experimental data in parameter setting P10.
   Solution| Temperature compensation factor| Solution| Temperature compensation factor
   ---|---|---|---
   NaCl| 2.12%/˚C| 10% Hydrochloric acid| 1.32%/˚C
   5% NaOH| 1.72%/˚C| 5% Sulfuric acid| 0.96%/˚C
   Dilute ammonia| 1.88%/˚C| |

6. *1000μS/cm =1mS/cm; 1000 ppm = 1 ppt

6. TDS and conductivity is linear related, and its conversion factor is 0.40-1.00. Adjust the factor in parameter setting P13 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.
7. Conversion Example if conductivity measurement is 1000µS/cm, then the default TDS measurement will be 710 ppm (under the default 0.71 conversion factor), and the salinity be 0.5 ppt.
8. For the self-diagnosis information, please refer to the table below:

1.Make sure the probe is fully submerged in the solution.
2.Check if the standard solution is expired or contaminated.
3.Check if the conductivity electrode (two black rods) is damaged.
4.Check if the conductivity electrode is contaminated. If so, please use a soft brush with warm water to clean up.

2. Auto. Lock (P02) – Users can set the auto lock time from 5 to 20 seconds. For example, if 10 seconds is set, when the measured value is stable for more than 10 seconds, the measured value will be automatically locked, and the HOLD icon will be displayed. Short press to release the lock. When the setting is “Off” , the Auto. lock function is turned off, that is, the measured value can only be manually locked. Short press ****to lock or unlock the measured value. The HOLD icon will be displayed when reading is locked.
3. Auto. Backlight (P03) ─ Users can set the automatic backlight time for 1 to 8 minutes. For example, if 3 minutes is set, the backlight will turn off automatically after 3 minutes; when the “Off” is set, the auto. backlight function will be turned off, and short press ****to manually turn the backlight on or off.
4. Auto. Power off (P04) ─ The auto. power off time can be set to 10 to 20 minutes. For example, if 15 minutes is set, the meter will automatically shut down after 15 minutes if no operation; when “Off” is set, the auto. power off function will be turned off. Long press ****to manually shut down the meter.
5. Conductivity Calibration Reminder (P07) – set X hours (H) Or X days (D) in ZenTest mobile app – settings – Parameter – pH – Calibration Reminder. On the meter, you can only check the values that’s been set up on ZenTest App. For example, if 3 days is set up, the Er6 icon (see Figure-4) will appear in the lower right corner of the LCD screen in 3 days to remind you to perform calibration, also in the ZenTest App there will be a pop-up reminder. After calibration is finished or the reminder setting is cancelled in the ZenTest App, the Er6 icon will disappear.
6. Conductivity Back to Factory Default (P08) – Select “Yes” to recover instrument calibration to theoretical value. This function can be used when instrument does not  work well in calibration or measurement. Calibrate and measure again after setting the instrument back to factory default.
