HI9033andHI9034multi‑rangeconductivityandTDSmeters,havebeen
designed for extended use in wet, humid, dusty and muddy conditions.
These meters utilize the latest in four‑ring potentiometric technology
which has been proven to provide higher accuracy than the common
amperometric method.
HI9033 can measure conductivity in four ranges. This allows the user to
analyze samples from deionized water to brine without having to switch
or recalibrate the probe.
HI9034 measures total dissolved solids (TDS) in three ranges to offer the
highest accuracy when performing measurements in diverse applications
suchasHVAC,wastewatertreatmentandreverseosmosis.Allthreeranges
can be activated at the touch of a button without having to change the
probe.
Both meters perform measurements with ATC (automatic temperature
compensation) which adjusts for the effects of temperature.
These portable instruments also feature BEPS (Battery Error Prevention
System) technology that alerts the user when low batteries could affect
the readings.

OPERATIONAL GUIDE
INITIAL PREPARATION
Each meter is supplied complete with a 3x1.5V batteries. Remove the
back cover, unwrap the battery and install it while paying attention to
its polarity (see "Battery Replacement" section).
Connect the probe to the meter securely by
aligning the pins with the socket, pushing
the plug in and tightening the threaded ring.
Make sure that the sleeve is properly inserted on the probe, with the
holes towards the top of the probe (i.e. the end nearest to the cable).
Make sure that the meter has been calibrated before taking any
measurements (see "Calibration" section for details).
If probe is not connected, the LCD will displays ''‑‑‑'' on both LCD lines.
TAKING MEASUREMENTS
To take measurement, place the probe into
the solution to be tested while making sure
that the holes are completely submerged. Tap
and stir the probe to remove any air bubbles
trapped inside the PVC sleeve.
Turn the instrument on by pressing the
ON/OFF key, and then select the desired range
by pressing the corresponding key.
The instrument will display all used tags for
few seconds followed by the battery capacity.
10
If the probe is not connected the instrument will
display dash lines.
If the LCD displays range limit blinking, the meter
is out of range and the solution measured exceeds
the selected range. In this case, the next (higher)
range should be selected.
TEMPERATURE EFFECT
HI76302W conductivity probe features
a built‑in temperature sensor that allows
automatic compensation of the reading for
any temperature differences.
Wait for a few minutes for the temperature sensor to reach the thermal
equilibrium with the test solution before taking measurements. If the
temperature of conductivity probe and solution is drastically different,
a longer time should be allowed.
AFTER MEASUREMENTS
When all measurements are completed, turn the meter OFF and clean
the probe (see "Probe Maintenance" section for details).
Note: Probe body and sleeve are made of PVC, and are susceptible
to damage due to temperatures exceeding 60 °C (140 °F). If the
probe is exposed to high temperature, the bond between the rings
and the probe body may become impaired and the probe will not
function properly. In this case, the probe will need to be replaced.
