OPERATION
·Remove the protective cap. Do not be alarmed if white crystals appear around the cap. This is normal with ORP electrodes and they dissolve when rinsed with water.
·Turn the meter on sliding the switch on the top.
·Immerse into solution up to the max immersion level.
·Stir gently and wait until the display stabilizes.
·After use, switch off ORP meter,, use the water clean the electrode and replace the protective cap.
Do not use distilled or deionized water for storage purposes.
·Large fluctuations in readings could be due to lack of calibration, dry electrode or rundown batteries.
Attention :during 2-3 weeks, put electrodes in 3mol/L KCL solution for 12 hours, to make sure the reading within accuracy.
