P5 TROUBLESHOOTING
ORP electrode cleaning:
If sensing element got contaminated, it will result in
slow response and inaccu rate reading. Clean it as
following:
(1) If contamination is a mineral matter, put sensing
element in HCL solution 0.1N for 10 minutes and
then rinse it with distilled water.
(2) If the contamination is oil or grease coating,
clean sensing element with detergent and rinse
with distilled water.
7. TROUBLESHOOTING
Power on but no display
1. Make sure the time of pressing power key is more
than 1 second.
2. Check the battery are in place and make good
contact and correct polarity.
3. Replace with new batteries and try again.
4. Move away the batteries for one minute and then
put back again.
Slow response
Clean probe by immersing the electrode in tap
water for 10-15 minutes, then rinse thoroughly with
distilled water or use a general-purpose electrode
cleaner.
LCD display E02, E03
Out of ORP measuring range. Check in normal
condition first, if remaining showing E02 or E03, the
electrode is out of order.

reading (E1) should be 86±15mV.
(2) Rinse electrode with distilled water, then set it in
bu ff er s olu ti on of pH4 .0 1 with sa tu rated
quinhydrone. After stabilizing, record mV meter
reading (E2). The difference between E1 and E2
should be 165mV.
