PRELIMINARY EXAMINATION

5
HI99300 and HI99301 are conductivity, total dissolved
solids and temperature measurement encountered in man‑
ufacturing and environmental testing protocols.
To increase precision, two models are available, with dif‑
ferent conductivity ranges, for applications from purified to
brackish waters.
All operations, settings and temperature scale selections,
are made through only 2 buttons.
The housing is waterproof and rated for IP67 conditions.
The supplied multi‑parameter probe, HI763063, includes
EC/TDS and temperature in one convenient, rugged probe.
Other user selectable features include different TDS factors
from 0.45 to 1.00, and a range of temperature coefficients
(b) from 0.0 to 2.4% for better solution temperature com‑
pensation.

Each meter is supplied with batteries. Before using the meter
for the first time, open the battery compartment
and insert batteries, observing the polarity
(see “Battery Replacement“).
TO CONNECT THE ELECTRODE
With the meter turned off, connect the HI763063 probe to
the DIN socket on the bottom of the meter by aligning the
pins and pushing in the plug firmly. Remove the protective
cap from the probe before taking any measurements.
TO TURN THE METER ON
To turn the meter ON, press the button on the front of
the meter. If it does not turn on, make sure that the batteries
are properly installed in their place.
The meter is provided with an active acoustic signal when
a key is pressed.
At start‑up the meter displays all LCD segments for a few
seconds, followed by the percentage indication of the
remaining battery life, displaying “WAIT“ until electrode
check is in process then the meter enters the normal mea‑
surement mode.

Note: The meter detects the presence and the type of the
probe at its input.
- If the probe is not connected the message “NO”
”PROBE“ appears alternatively on the secondary LCD.
- If the probe is not compatible “WRONG” ”PROBE“ mes-
sage appears alternatively on the secondary LCD line with
“---“ blinking on the first LCD line.
- If the readings are out of range, the nearest range limits
are displayed blinking (E.g. 3999 μS -5.0 °C).
TO SELECT THE MEASUREMENT RANGE
While in measurement mode, press the SET button to select
EC or TDS measurement on the LCD.
TO FREEZE THE MEASUREMENT VALUES
While in measurement mode, press and hold the SET
button until “HOLD“ appears on the second LCD line for
1 second. The reading of EC and temperature will be frozen
on the LCD with “H” blinking.
Press any button to resume active measurements.
