Steps
1. Select the appropriate Electrode according to the tested solution, insert the Electrode plug into the socket, align the groove and the convex groove, and press the top until you hear the "click" sound
2. Open the battery cover, load 4 1.5V batteries (pay attention to the positive cathode), press the "power on" button to turn on the power, and warm up for 5 minutes
3. Wash and dry the Conductivity detector Electrode, put it into the solution, place it still after agitation, and wait for the Measured value to stabilize, which is the solution conductivity value
4. Calibration method: Press the "calibrate" key to enter the calibrate mode, insert the 1408μs/cm standard calibration head into the Electrode seat, wait for the Measured value to stabilize and then press the "calibrate" key, the LCD display flashes "1408μs/cm", after a few seconds, display "End" to return to Measurement mode
Notice
• Ambient Temperature: 5~ 35 ℃; relative humidity: < 85%
• Power supply: 220V +/- 10% 50Hz +/- 1Hz
• Avoid significant vibration and strong magnetic field interference other than the geomagnetic field
• Electrode plug when pulling out, pinch the plug and pull it out
• The instrument has been calibrated when it leaves the factory, and can be used directly under normal circumstances
