OPERATION
yThe meter is supplied complete with a 9V battery.
Slide o the battery compartment cover located
on the back of the meter. Install the battery into the
battery clip connector while observing polarity.
yAlways remove the electrode protective cap before
taking any measurement. If the electrode has been
left dry, soak the tip in storage solution for a few
minutes to reactivate it.
yConnect the ORP electrode to the BNC socket on the
top of the meter.
yImmerse the tip (2.5 cm) of the ORP electrode into the
sample.
yTurn the instrument on by pressing the ON/OFF key.
yAllow the reading to stabilize before taking
measurements.
yAfter use, switch the meter o and store the
electrode with a few drops of storage solution in the
protective cap.
yThe meter is factory calibrated. ORP electrodes are
interchangeable and no mV calibration is needed
when they are replaced.
MAINTENANCE:
yThe surface of the ORP electrode must always be
clean. Use M10000B rinse solution for this purpose.
If needed, clean the Platinum tip with very fine
abrasive paper.
yWhen not in use, the tip (reference junction) of the
electrode should always be kept moist and safe
from any mechanical stress.
