CONNECTIONS

Plug the 12 VDC adapter into the power supply socket.

Note: This instrument use non volatile memory to retain the calibration

parameters and all the other settings even when unplugged.

Connect the EC/TDS probe to the 7-pin connector. Tighten the threaded ring.

Make sure the probe sleeve is properly inserted, as shown below:

INSTRUMENT START-UP

• Turn the instrument on by pressing the ON/OFF switch.

• All LCD tags are displayed and a beep is generated while the instrument
performs self test.

TAKING MEASUREMENTS

Immerse the probe into the solution to be tested. The sleeve
holes must be completely submerged. Tap the probe repeat­edly to remove any air bubbles that may be trapped inside
the sleeve.

If needed, press RANGE repeatedly until the desired range (EC, TDS, NaCl) is
selected on the LCD (displaying µS[mS], ppm[g/L] or %).

Allow for the reading to stabilize. The upper LCD displays the measurement in
the selected range, while the temperature is displayed on the lower LCD.

7

Notes:

LOCK

• If the meter displays “----”, the reading is out of range.

• If the stability indicator “~” blinks, the reading is unstable.

• Make sure the meter is calibrated before taking measurements.

• If measurements are taken successively in different samples, for accu-

rate readings it is recommended to rinse the probe thoroughly with
deionized water before immersing it into the samples.

• TDS reading is obtained by multiplying the EC reading by the TDS

factor, which has a default value of 0.50. It is possible to change the
TDS factor in the 0.40 to 0.80 range by entering setup mode and
selecting the “tdS” item (see SETUP for details).

• When the use of an alternate function (SETUP, TC, GLP or CALT) is

requested, press and hold the ALT key first, and then the second key.

AUTORANGING

The EC and TDS scales are autoranging. The meter automatically sets the scale
with the highest possible resolution.

By pressing LOCK, the autoranging feature is disabled and
the current range is frozen on the LCD. “1” tag starts
blinking. To restore the autoranging option press LOCK
again.

Note: Autoranging is automatically restored if the range is changed, if the

setup or calibration modes are entered, or if the meter is turned off and
back on again.

TEMPERATURE COMPENSATION

Three options of compensating temperature are available:
Automatic (Atc): The EC probe has a built-in temperature sensor; the

temperature value is used to automatically compensate the EC/TDS reading
(from –9.9 °C to 120.0 °C), using the selected reference temperature.

Manual (Mtc): The temperature value, shown on the secondary LCD, can be
manually set with the ARROW keys. The compensation is referenced at the
selected reference temperature. The “°C” tag blinks when this option is active.

No Compensation (notc): The temperature value shown on the secondary LCD
is not taken into account. The reading displayed on the primary LCD is the actual
EC or TDS value. The “°C” tag blinks when this option is active.

Note: The default compensation mode is ATC.

8

To select the desired option press ATC until the option is

CAL

BUF

ALT TC

CAL

ATC

displayed on the LCD.
If temperature compensation is active, measurements are

compensated using the temperature coefficient (default value

1.90 %/°C).

To change the temperature coefficient, enter the setup mode and select the “tc”
item (See SETUP for details, page 14). The current temperature coefficient can be
quickly viewed by pressing ALT+TC keys. The value is briefly displayed on the
secondary LCD.

• If the temperature reading is out of –9.9 °C - 120.0 °C interval and Atc or
Mtc option is selected, the temperature limit range value will be displayed,
together with the “°C” tag blinking and the instrument will do no
temperature compensation.

EC/TDS CALIBRATION

EC calibration is a one-point procedure. Selectable calibration points are:

0.00 µS, 84.0 µS, 1413 µS, 5.00 mS, 12.88 mS, 80.0 mS, 111.8 mS.

To enter EC calibration, select the EC range and press CAL.

Note: TDS reading is automatically derived from the EC reading and no

specific calibration for TDS is needed. Pressing CAL when TDS range is
selected has no effect.

Rinse the probe with calibration solution or deionized water.
Immerse the probe into the solution. The sleeve holes must be
completely submerged. Tap the probe repeatedly to remove any
air bubbles that may be trapped inside the sleeve.

For zero calibration, just leave the dry probe in the air.
The “BUF” and “CAL” tags are displayed. The primary LCD displays the

uncalibrated EC reading. The secondary LCD displays the buffer value. The
“~” tag blinks.

When the reading is stable, “CFM” tag starts blinking on the LCD, asking for
confirmation. Press CFM to confirm calibration.

The instrument displays the “Stor Good” message and returns to measurement mode.

Notes:

• If the uncalibrated reading is too far from the expected value or the

temperature value is out of 0 – 60 ºC range, calibration is not recognized.
The “CFM” tag does not appear; the “~” and “BUF” tags blink to signal
wrong or contaminated calibration solution. If the temperature value is out
of 0 – 60 ºC range, the “ºC” tag will also be displayed blinking on the LCD.

• For best results choose an EC buffer value close to the sample to be measured.

• In order to minimize any EMC interferences, use plastic beakers.

• The meter uses 1.90 %/°C compensation factor during calibration. If

the setup item “tc” has been set to a different value, when exiting
calibration mode, the displayed value on the upper LCD might be
different from the nominal buffer value.

• It is possible to set the cell constant value directly, without following the

calibration procedure. To set the cell constant enter the setup mode
and select “CEL” (see SETUP for details).

NaCl CALIBRATION

NaCl calibration is a one-point procedure at 100.0% NaCl. Use the
HI 7037L calibration solution (sea water solution) as a 100% NaCl
standard solution.

To enter NaCl calibration select the NaCl range and
press CAL.

Rinse the probe with some of the calibration solution or
deionized water. Immerse the probe into HI 7037L
solution. The sleeve holes must be completely submerged.
Tap the probe repeatedly to remove any air bubbles
that may be trapped inside the sleeve.

TEMPERATURE CHART

The conductivity of an aqueous solution is the measure of its ability to carry an
electrical current by means of ionic motion.

The conductivity invariably increases with increasing temperature.
It is affected by the type and number of ions in the solution and by the viscosity

of the solution itself. Both parameters are temperature dependent. The de­pendency of conductivity on temperature is expressed as a relative change per
Celsius degree at a particular temperature, commonly as percent per ºC.

The following table lists the temperature dependence of the HANNA calibra­tion buffers.

GOOD LABORATORY PRACTICE

Good Laboratory Practice (GLP) is a set of functions that allows storage and
retrieval of data regarding the status of the system.

After a successful calibration, the meter automatically stores the date and time
of calibration, the used calibration solution and the resulting cell constant
value. All this information can be recalled by the user.

To view the last calibration data, select the
desired range (EC or NaCl) and press
ALT+GLP keys.

The first information appearing on the LCD is the meter “id” code.

15

By repeatedly pressing RANGE, GLP data is displayed in the following

BUF

RANGE

order:
Last calibration date:

Last calibration year:

Last calibration time:

Cell constant value (K):

Offset value:

This information is displayed only if the last calibration was performed at 0.00 µS.
Calibration solution used:

If the cell constant was changed after calibration (through the “CEL” setup
function), this information is not displayed.

For NaCl GLP, the last parameter is not the nominal value of the calibration solution
but the actual conductivity and the temperature of the used calibration solution.

or ALT+GLP keys to return to measurement mode.

• Last calibration data is available for EC and NaCl only. No calibration
data can be recalled for TDS. If the meter is in TDS mode, by pressing
ALT+GLP keys it is possible only to view the ID code. Press ALT+GLP
keys again to return to measurement mode.

• The meter has an internal lithium battery that allows to correctly
update the date and time even if the power supply is disconnected.

DATA TRANSFER TO PC

Connect the meter to a PC through the RS232 output. Use HI 920010 (9 to
9-pin) connection cable.

The meter must be in measurement mode to communicate.

The meter port is optoisolated and transmits data with a Baud rate of
2400 bps.

The user can retrieve the GLP data, request meter’s parameters and the
current reading (current range only) from the PC directly. It is also possible to
send a command from the PC to change ranges.

To communicate with the PC use the optional HI 92000 communication
software. The software is provided with an exclusive on-line guide of all the
commands available and allows data printing, plotting and exporting.

PROBE MAINTENANCE

Rinse the probe with clean water after measurements. If more cleaning is
required, remove the probe sleeve and clean the probe with a cloth or a
nonabrasive detergent. Make sure to reinsert the sleeve onto the probe
properly and in the right direction. After cleaning the probe, recalibrate the
instrument.

The platinum rings are sustained with glass. Take great care while handling
the probe.
