Care and Maintenance
To obtain the highest accuracy for measurements it is important to follow these tips:
• Calibration is only as good as the buffer being used. The pH buffer values change over
time once the sachets are opened. Fresh buffer should be used for each calibration.
• Rinse the probe in purified water after use in pH buffers and between measurements
of samples.
• When the meter is not in use it is important to add several drops of storage solution
to the protective cap to keep the probe hydrated. If storage solution is not available,
pH 4.01 or pH 7.01 buffer can be used.
• For improved accuracy it is recommended to calibrate in two buffers.
• It is important to calibrate and measure samples at the same temperature. A dramatic
change in temperature between buffer solutions and samples to be tested will give
inaccurate readings.
• If fouled, clean the electrode by soaking in cleaning solution for 20 minutes, then
rinse the tip and soak in storage solution at least 30 minutes before use. Recalibrate
after each cleaning.
The meter features a low battery indicator. When
the battery is running low, the tag will blink on
screen. When the battery has been depleted,
“Erb” will appear on screen and the meter will
turn off.
Place meter in calibration mode. Press and hold
ON/OFF until “CLr” is displayed. The meter will
now be at default calibration. No tags will be
shown in measurement mode until calibration is
performed.

“Err” Message
Battery Indicator
From measurement mode, press and hold the
ON/OFF button. The meter will cycle through
“OFF,” “CAL,” then current auto-off setting.
The default setting is 8 minutes (“d08”). Press
ON/OFF button to change. “d60” is auto-off after
60 minutes, and “d--” disables the auto-off
feature. Press and hold the button to exit the
menu.
