PRELIMINARY EXAMINATION

GENERAL DESCRIPTION and INTENDED USE
The HI991300 and HI991301 are light weight, portable
pH, conductivity (or total dissolved solids) and temperature
meters for portable applications requiring both a pH and
conductivity (or TDS) measurement. Applications include
measurements for greenhouses irrigation, hydroponics and
groundwater monitoring from agriculture nutrient pollution.
The HI991300 and HI991301 meters feature 2 button
operation and are simple to use. All operations and set‑
tings, including calibration buffers and temperature scale
selections, are made through these 2 buttons. They have
a waterproof and compact casing rated for IP67 conditions
and a large Tri‑line display. The meters have automatic pH
calibration at one or two points and a single conductivity
calibration. 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 conductivity or
TDS solution temperature compensation. These meters are
supplied with a multi‑parameter probe specifically designed
for these meters. To increase conductivity accuracy, two me‑
ter models are available, with different conductivity ranges,
for applications from purified to brackish waters.
The HI12883 multi‑parameter probe, incorporates a
domed shaped pH bulb rated from 0‑13 pH, a single
junction Ag/AgCl reference electrode with gelled electro‑
lyte and a retractable cloth wick junction, a graphite EC/
TDS cell, and a temperature sensor in one convenient,
rugged polypropylene body. In addition, to ensure against
interference from transient electrical noise to pH, a solid‑
state preamplifier is integrated into the probe. The probe
is rated from 0 to 50°C.

DISPLAY DESCRIPTION
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 HI12883 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
measurement 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 third LCD.
- If the probe is not compatible “WRONG” ”PROBE“
message appears alternatively on the third LCD line with
“---“ blinking on the first LCD line.
- Compatible pH probe: HI12963, HI12943, HI10483 pH
probes and HI763003 EC probe. If one of the probes
are detected “NoEC“ or if HI763003 is connected
“NopH“ message is displayed at start-up and “---“
message displayed on the secondary LCD for the pH
probes and on the first LCD if the EC probe is connected.
- If the readings are out of range, the nearest range limits
are displayed blinking (E.g. -2.00 pH -5.0 °C).
TO SELECT THE MEASUREMENT RANGE
While in measurement mode, press the SET button to select

on the LCD with “H” blinking.
Press any button to resume active measurements.
TO ENTER CALIBRATION MODE
Press and hold the button until ”POWER” and tag
is replaced by “PH STD“, tag or “EC STD“,
tag if standard calibration is selected from setup menu.
Release the button.
TO ENTER SETUP MODE
Press and hold button until “EC STD“ and tag is
replaced by “SETUP“ and tag. Release the button.
TO TURN THE METER OFF
Whileinmeasurementmode,pressthe button.”POWER”
and tag will appear. Release the button.
pH MEASUREMENT & CALIBRATION
Make sure the meter has been calibrated before use.
If the probe is dry, soak it in HI70300 storage solution for
30 minutes to reactivate it. If fouled,
clean the electrode by soaking in clean‑
ing solution for 20 minutes, then rinse
the tip and soak in storage solution at
least 30 minutes before use.
Rinse the electrode off well and shake off excess droplets.
Recalibrate before using. Submerge the probe in the sample
to be tested while stirring it gently. Wait until the tag
on the LCD disappears.
The LCD displays the pH value (automatically compensated
for temperature) on the primary LCD, the EC, TDS or pH‑
mV value on the secondary LCD, while the third LCD
