6~INSTALLATION
Figure 1: Back panel battery cover fitted
Figure 2: Back panel battery cover removed
6~1 Battery
ATEX applications use only Energizer L92 batteries, 2
required. Do not use any other type, or mix batteries with any
other type. Batteries must be replaced in the safe area. Follow
the procedure below. When the cap assembly is removed and
disconnected, transport cap assembly to the non-hazardous
area. When the batteries are replaced, be sure the battery
cover is fitted before returning to the hazardous area. Failure
to perform the battery replacement correctly may result in an
unsafe system.
Please observe the above battery warnings. Refer to Figure 2
(Observe polarity). Battery type 1.5 V Lithium ENERGIZER L92
AAA size offering longer life at high temperature: must be used for
ATEX applications.
To fit or replace batteries, use the following procedure:
Note: If fitted, the battery isolation tab will need to be removed
before use.
1
Turn the cap retaining ring anti-clockwise until the ring
releases from the enclosure body.
2
Remove the cap assembly from the enclosure base, un-
plug the 4-way connector. The cap assembly should
now be totally free from the base.
3
For ATEX applications: at this stage, if not already
in a safe area, the cap must be transported to a safe
area.
4
Remove the battery cover by unscrewing the two
retaining screws. If fitted, remove the batteries to be
replaced.
5
Fit new batteries. Observe the polarity symbols marked
on the battery holder.
6
Replace the battery cover, ensure the information label
is visible. Secure the two retaining screws.
7
For Atex applications, return the cap assembly to
the hazardous area.
8
Inspect the cap O ring seal for correct alignment.
Reconnect the 4-way plug and site the cap assembly
back on the case base.
9
Tighten the retaining ring until it stops turning smoothly.
At this point, tighten an additional 1/12 of a turn.
Use the indents on the retaining ring to gauge 1/12 of a
turn as 12 indents are equally spaced around the
retaining ring.
Please dispose of batteries in a responsible way
6~2 Maintenance
The following maintenance is required.:
Battery replacement: the expected battery life in normal
operation well exceeds 1 year; the exact life depends on many
factors such as the number of log reads, response time and the
ambient operating temperature. A low-battery warning is
displayed when the batteries’voltage approaches discharge. It
is recommended at this time the batteries are replaced within a
month.
If required, the device may be cleaned with a damp cloth. For
ATEX applications please refer to “ATEX Applications Special
Conditions for Safe Use” for further information on cleaning.
The device uses advanced circuitry and high stability
components to maintain accuracy. For recalibration, the device
must be returned to the supplier for factory calibration. A single
point offset trim is provided to cancel any sensor error if
required.
The device contains no other user-serviceable parts. Please
return faulty units to your supplier for factory repair or
replacement.
6~3 Sensor wiring
Figure 3: Connection diagram
Important –unplug the 4-way sensor connector from the
device during wiring, re-connect when wiring is complete.
Ensure the sensor wires are long enough (80 to 100 mm) to
allow easy access for reconnecting the plug to the device and,
if required, access to the configuration switch.

D2629-01-04 CN5795 User guide
6~3 Sensor wiring (continued)
General –the instrument is designed to be directly attached to the
sensor probe assembly. Remote Probes may be used but the user
must ensure all sensor entries maintain environmental protection to
at least IP65 rating. To comply with CE EMC requirements the
sensor wires should be no longer than 3 metres. When using an
RTD, for best results we recommend using three-wire connection;
this method compensates for any lead resistance between the
sensing element and instrument. Two-wire RTD connection is
possible by linking pins 1 and 3: refer to Figure 3.
Thermocouple wire type must be maintained from the sensor
element to the instrument terminals. The terminals are effectively
the cold junction point and can be displayed as “Tamb” ambient
temperature.
7~USER CONFIGURATION.
IMPORTANT
READ COMPLETE SECTION BEFORE ATTEMPTING
CONFIGURATION
The device is configured using a single push button and a series of
menus displayed on the LCD screen. The push button is internally
located and is intended for configuration and commissioning

A single push-button is provided together with
a simple configuration menu for configuration.
The following variables can be configured:
sensor type, temperature unit, decimal place
and offset.
Single press, in display mode to enter the menu lists.
The configuration settings are presented as a series of menu lists.
A single press (click) from display mode is used to enter the
configuration menu lists.
The order of the menu lists options is as follows:
•Sensor type.
•Display unit.
•Decimal place.
•Response time.
•Offset.
•Pass code.
Long Press > 2 seconds, in configuration mode
To advance through the menu option lists, press continuously for
over 2 seconds. This action is used to advance to the next option
in the menu list and to confirm a selection, and when a variable
has been selected.
Single press and Double press, in configuration mode
A single press (click) from configuration mode. This action steps
through the selected menu list variable, e.g. sensor menu list
variable = Pt100 Eu, single press will select Pt100 US. A double
press steps through the list in reverse order.
No press > 12 seconds, in configuration mode
To escape from the configuration menu, allow a period of 12
seconds with no button action.
Alternatively, stepping through the menu list options will return the
device to the run mode.

IMPORTANT
NFC functions are only to be carried out in the safe area or with a
suitably approved ATEX NFC device.
7~3 NFCLink software configuration
The NFC interface allows the instrument to communicate with an
Android device using NFC connectivity.
The prime function of the interface is to configure the device using
the free app, which is available for downloading to Android
devices.
The app allows the user to set the parameters shown in the
configuration screen (below).
Tag No and Contact are free type fields, saved onto the device.
Latitude and Longitude can be used to add the unit’s location
which is added to the log in the NFCLogLink software.
Read process screen showing maximum and minimum values
since the last clear command.
Configuration screen
7~4 NFC Loglink configuration software
The NFC interface allows the instrument to communicate with an
Android device using NFC connectivity.
The prime function of the interface is to read logged data from the
device using the free app, which is available for downloading to
Android devices.
The app allows the user to read existing logs, change the log
manifest, start a new log, synchronise the instrument clock and
reset the maximum/minimum readings.
Logs can run to a fixed number and stop or continually roll over. Up
to 1500 log points can be recorded. The start of the log can be
delayed up to one month.
Data from NFCLogLink can be viewed on screen as a graph or
table and can also be saved to a csv file.
Note: For larger logs the data may take over a minute to fully
download via the NFC interface.
Note: Not all Android devices fully implement the near field
communication (NFC) standard and may not hold the full 1500 log
points.
