Description
Steps: 1ve the protective cover. 2h the “ON/OFF” switch to turn on the power. 3 the electrode into the solution to be tested, shake it gently,and read the displayed value after the value is stable. 4h the “HOLD” button to keep the current measured value. If you need to re-measure,press the “HOLD” button again to automatically release the hold status. 5r use,press the switch, wash the electrode with distilled water,and put on the protective coverautions: 1:There is a white crystalline salt around the electrode,which is a normal phenomenon of the ORP electrode. 2:When testing the ORP value,it usually takes about a few minutes to about 10 minutes for the value to stabilize and jump very slowly or read the displayed value as the measured value. 3:The display value in ORP and air is jumping,it is normal phenomenon that there is no regular change. 4:After use,please turn off the power, wash the electrode with pure water or distilled water,use a soft tissue to dry the water and put on the protective coveriation: Measuring range: 0~±1999mg/LmV Resolution: 1mV Accuracy: ±5mV Working voltage: 4 x 1.5V (AG-13 battery) (Not included the battery) Working temperature: 0 ° C ~ 50 ° C Correction:1 point correction Size:188 x 35 mm / 7.40 x 1.38 inch (appr.)
