Nin I still understand that batteries also go by reading the various reviews. There is nothing that explains whether the device is to be traced back to the first use or is already calibrated. In any case, you should also supply the calibration fluids ... also because where do I find these sachets? Please tell me which pile.ch we go with.

the pen came in a box that was 100% intact. instructions in English only. no calibration liquid, I will be the one but in the purchase it was not clear if it was understood or not. anyway, when you got the liquids it's easy to calibrate. the display is not the best, it does not have much contrast, especially the temperature part. accuracy is good. it does not have a suitable packaging to be stored. overall a good product at a great price.

Hi! What kind of batteries do they need? An Italian translation of the instructions? Answer aspect, best regards, thanks. OPERATION 1. Remove the protective cap. 2. Clean the electrode with distilled water, Andr dry the water attached to the electrode with filter paper. 3. Press the ON / OFF button to turn on the power. 4. Insert the instrument into the test solution, with the measuring electrode immersed in, and mix gently. 5. Press "986-TDS / PH (983-CE / PH)" to select "TDS / CE" or "pH", wait for the digitalis to be stable, read the final value. 6. After using, washing electrodes, press the ON / OFF button to turn off. PH calibration 1. Immerse the pH electrode in pH 6.86 (below the temperature of 25 ° C) of the standard phosphate liquid, mix lightly. 2. Press "986-TDS / pH (983-EC / pH" to select "pH". Adjust the "pH7" trimmer with a screwdriver to obtain the buffer solution value corresponding to the measurement temperature. 3. Use the distilled water clean the electrode, immerse the standard pH 4.01 or pH 9.18 electrode in the standard buffer solution, after about one minute, until you get the value of the buffer solution corresponding to the measurement temperature 4. Value Display and pH value of the buffer solution within range of error. (986) TDS calibration 1.Press "TDS / pH" to select "TDS" mode, then immerse the TDS electrode in the standard 6440ppm buffer solution, and shake slightly. the display value is stable, adjust from the bottom "TDS" until you see 6440ppm. Wash the electrode in distilled water and dry it with filter paper (983) EC calibration 1. Press "Ec / pH" to select the mode "CE", then immerse the CE electrode in 12 882us / cm standard buffer solution and shake slightly. 2. When the display value is stable, adjust from the bottom "CE" to its 12880us / cm hows. Wash the electrode in distilled water and dry it with filter paper. 3. Immerse the device in standard value of the solution showing and standard solution in the range of error 1413us / cm. In situations below, the devices must be recalibrated. -Electrode Is place to be new -view Been used (or placed) for a long time after calibration -electrodes are very often used precision is required -High PRECAUTIONS 1. During the test please mix the electrodes, and avoid the bubbles on it. Otherwise it will affect the result. 2. If the error is too large or TDS value (EC) is not going back to 0, dip TDS electrode in ethyl alcohol and shake for 5-10 seconds to wash the electrode. battery Install If the screen gets dark or fuzzy, or the error is large, the batteries should be replaced. Just take out the battery cover plate and replace it. Pay attention to the verse.
