GENERAL DESCRIPTIONGENERAL DESCRIPTION
GENERAL DESCRIPTION
GENERAL DESCRIPTIONGENERAL DESCRIPTION
The Hanna Instruments portable NTC thermometers with built-in printers are microprocessor-based and enable you to accurately measure
temperature and record data.
The instruments housing is made of rugged and lightweight material
making it truly portable.
The meters come equipped with an easy-to-read LCD with backlight
feature for comfortable reading even in dark environments.
A user friendly interface provides clear messages regarding errors,
functions and more.
The GLP features provide a guarantee of data consistency.
Measurements can be performed with lab-grade precision in the field as
well as in the laboratory.
An alarm time-out is available to alert the user if too much time has
elapsed since the last calibration and that re-calibration may be
required.
The meters provide a GLP settings through a password protection
method.
The Battery Error Preventing System (BEPS) recognizes batteries levels
as they become weaker.

To prolong battery life, the backlight and printing features are disabled when the batteries are getting low; "LOBAT" indication is displayed
on LCD to warn the user of this condition. However, the meter continues to measure correctly even when the low battery indication is
displayed. The meter automatically switches itself off when the batteries are too weak to support proper function.
The meters are equipped with an internal lithium battery that powers
the clock circuit even in the absence of power supplies.
For long term field and lab applications, these meters can be connected
to a 12VDC adapter.

INITIAL PREPARATIONINITIAL PREPARATION
INITIAL PREPARATION
INITIAL PREPARATIONINITIAL PREPARATION
Each meter is supplied complete with batteries. Remove the back
cover, unwrap the batteries and install them while paying attention to
the polarity. Alternatively, connect the HI 710005 or HI 710006
voltage adapter to the power adapter plug.
To prepare the instrument for use, choose the most appropriate temperature probe(s) for your application (see accessories) and connect it
(them) to the connector(s) located on the top of the instrument.
All the probes have been precalibrated at the factory and no calibration is needed.
With the meter facing you, channel #1 is the first connector on the
top left hand side.
To switch the meter on, press the ON/OFF key.
The batteries charge status or "LINE" message
(if external power adapter is connected) will be
displayed on the LCD for a few seconds.
ON/OFF
The meter is now ready to operate.
To maximize battery life, the meter is automatically switched off after a
user selectable period of non-use (this feature is enabled and set to 5
minutes by default; it can be disabled or changed through setup code
40). If in logging mode, after the period of non-use, the meter will
continue to monitor the temperature periodically at the end of every
logging interval. Only the "LOG" indication will be visible on LCD.
While storing data in memory, during the sleep mode, the reading will
appear briefly on the LCD.
To reactivate the display press the ON/OFF key.
Note: When the use of an alternate function (FNC, CFM and LOT
INFO) is requested, press and hold the ALT key first and then
the second listed key.

SETUP MODESETUP MODE
SETUP MODE
SETUP MODESETUP MODE
Setup can be used to view data regarding instrument status (e.g.
battery charge) or GLP data (e.g. calibration date) or to view or print
the logged data. It also allows the user to change the meter parameters (e.g. time) and to gain access to stored data.
• To enter this mode ensure the meter is
not logging and then press the ALT and
FNC keys.
PASSWORD PROTECTION
Setting of the GLP parameters (calibration alarm time-out, instrument
ID code, time and date) can be password protected. If password is set
to a value different from 0000 (factory setting), the user will be asked
to enter the password.
• Select the desired GLP parameter code.
• Enter the password by the arrow keys.
• The scrolling message "Insert the function code or press "ALT" -
"FNC" to escape" in the upper LCD and the indication "F 00" with
the first digit blinking in the lower LCD will be displayed.
• Enter the first digit of the code of the parameter you want to set
using the Ç or È key and pass to the next digit with Æ. The
second digit will start blinking.
• Enter the second digit using the Ç or
È key.
• Press ALT and CFM to confirm the code.
• If the entered code doesn't exist the "Err"
message will be displayed for a few seconds and then the message "Insert the
function code or press ALT - FNC to escape" will recommence scrolling in the
upper LCD.
• Press the ALT and CFM keys to
confirm.
• If password is wrong the meter will return to the function selection
mode without any warning message.
• If password is correct, the meter provides access to the parameter.
PARAMETERS SETTING
• Once the parameter code has been entered, the appropriate message will scroll across the LCD for a few seconds.
• The current value of the selected parameter on the upper LCD and
the parameter code on the lower LCD will be displayed. The first
digit will blink if the parameter can assume continuous values. All
the digits will blink if the parameter can assume only a fixed set of
values.
• Enter the new value using the arrow keys.
• Press ALT and CFM to confirm the value.
