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.
BATTERY REPLACEMENT
When the battery becomes weak the meter will
display “ “, the low battery indicator. The battery
has about 50 hours of working time left. A low battery
will result in unreliable measurements. Prompt battery
replacement is required.
Battery replacement must only take place in a non
hazardous area using an alkaline 9V battery.
Turn the meter o, slide the battery compartment
cover located at the rear of the meter o and replace
the 9V battery with a new one. Make sure the battery
contacts are fully engaged in the connector, seat the
battery in its compartment and replace the cover.
