OPERATION:

• The meter is supplied complete with a 9V battery. Slide off

the battery compartment cover located on the back of the

meter. Install the battery into the battery clip connector

while observing polarity.

• Always 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.

• Connect the ORP electrode to the BNC socket on the top

of the meter.

• Immerse the tip (2.5 cm) of

the ORP electrode into the

sample.

• Turn the instrument on by

pressing the ON/OFF key.

• Allow the reading to stabilize

before taking measurements.

• After use, switch the meter

off and store the electrode

with a few drops of storage

solution in the protective

cap.

• The meter is factory

calibrated. ORP electrodes

are interchangeable and no

mV calibration is needed

when they are replaced.
