Quick Reference Guide
TAKING MEASUREMENTS
• Connect the HI 1285-6 probe and switch the meter ON.
• Submerge the probe into the sample to be tested.
• Select the desired measurement range (pH, mS/cm, ppm, °C)
by pressing the correspondent key.
Note: If the display shows only a “1”, the
meter is out of range.
• Wait for a couple of minutes for reaching
the thermal equilibrium before taking any
measurements.
• After use switch off the instrument, clean and cover the probe
with the protective cap.
Note: It is recommended to clean often the probe with HI 700661

BATTERY REPLACEMENT
When the battery level is so low that it may cause unreliable
measurements, the meter turns off.
It is recommended to replace the battery immediately.
Unscrew the three screws on the rear of the meter, remove the
battery compartment cover and replace the 9V alkaline battery
with a new one while observing its polarity.
Make sure the battery contacts are tight and secure before
replacing the cover.
