1~DESCRIPTION.

The DM650TM battery powered indicator accepts RTD or thermocouple temperature
sensors and displays the sensor temperature in °C or °F on a 6-digit LCD display. The
instrument offers an adva nced display m ode allowing the user to also display one or
two (1 to 32) ch aracter mess ages. Additional to the messages, the user may select an
alert event to occur when th e temperature is within a band. The chang e-over relay can
be used together with the messaging and alert to provide switching at user-set switch
points. In addition to this, on board datalogging is also available to record process
details at up to 5000 points.

2~RECEIVING AND UNPACKING.

Please inspect the packagi ng and instrument thoroug hly for any signs of transit
damage. If the instrument h as been damaged, please notify your supplier immediately.

3~SPECIFICATION.

Refer to data s heet for full specification.

4~ INSTALLATION AND WIRING.

4.1~MECHANICAL.

The instrument is a high acc uracy digital thermometer. In order to ensure correct
operation, t he following must be observed:
The product must be stored in a dry clean environment and remain in ori ginal
packaging pri or to installation.
The instrument must not be installed adjacent to electro-mechanical starters,
controllers, thyristor power units or el ectrical swi tch gear.
Any cleaning of the instrument must be done using a mild detergent and soft cloth. No
solvents or a brasive cleaners should be used.
Stated ambient operating conditions must not be exceeded. Battery life will r educe with
higher ambient temperatur e operating conditions.

4.2~ELECTRICAL.

For a wiring diagram please ref er to the rear panel of the DM650TM inside the
case housing.

Two-part connectors are used for input and relay connections, allowing the unit to be
easily remov ed from the hous ing for reprograming or data download if this is not
possible in s itu. On insertion of battery the unit will run through a power up check;
during this time the relay may change state.

IMPORTANT: Alw ays remove bat tery before any wiring takes place. Gain access to
the connectors and battery holder by twisting cap t o release front panel assembly from
case.
RTD: For best result we recommend using three wir e connection; this metho d
compensates for any lead resistance between the sensing element and instrument.
Two wire connection is possible: refer to connection diagram on the instrument
protection panel.
THERMOCOUPLE: T/C wire type must be maint ained from the sensor elem ent to the
instrument terminals. The terminals are effectively the cold junc tion point and can be
displayed as “ Case” temper ature.
RELAY CONNECTION: A relay with changeover cont acts is avail able. Screw terminals
are provided for connection for wire siz e 16 to 20 AWG. The relay contacts are rated at
48 VDC 28 VAC RMS @ 1 A (5 mA minimum curre nt) see DM650TM data sheet.
BATTERY: To remove battery, use screw driver to ease the positive end of the battery
out of holder. Insert new battery negativ e end first then press into place. (Observe
polarity). Battery type 3.6 V Lithium (2.4 A/Hr) CR14 505 (IEC) AA case style. Please
dispose of th e battery in a res ponsible wa y.

WARNING

For configuring, reading live data or re ading logged data if using a grounded
thermocouple probe on the input, it is important not to c onnect the programming USB
lead to a mains powered comp uter. It is pos sible to damage the instrument if
connected in t his way.
To avoid dama ge use one of th e following methods:

• Disconnect the pro be before configur ati o n, reconn ec t the pro be aft er
configuration.

• Ensure the probe and DM650 housing are not in contact wi th any conductive
parts during configuration.

• Use a laptop type computer running from its battery po wer supply, not connected
to a mains supply. This is rec om mended for r eading lived data or offsetting a unit
if already inst alled in the field.

• Use a USB isolator between the computer and the DM650.

5~USER CONFIGURATION.

IMPORTANT

READ COMPLETE SECTION BEFORE A TTEMPTING CONFIGURATION.
PARTICULAR CARE SHOULD BE TAK EN REGARDING TIMEOUTS IN MENU 2 & 3

The instrument is provide d with a USB interface for direct connection to a PC. Free
software USBSpeedLink is available. Pl ease refer to the USBSpeedLink software for
further information on configuration. The software can be downloaded from
www.status.co.uk.

DISPLAY: The display provid es six 14 segment characters for display of temperatur e
and alpha-numeric messages, together with a 8 segment bar graph and six icons. The
display is capable of operating in an ambient temperature range of ( -30 to 70) °C, but
at temperatur es lower than -5 °C (due to the slower LCD speed) scrolled messaging i s
not practical, so the displ ay will automatically rev ert to basic mode showing
temperature. The display’s high contrast, coupled wi th a digit heig ht of 7.9 mm, offers
clear readouts at low as well as high ambi ent light and direct sunlight.
The display l ayout is as follows:

5~USER CONFIGURATION (continued).

1. NFC - The Symbol is on when a NFC field is detected. When a detected field is lost the symbol
will turn off after a few seconds.

2. TRANSMIT/RECEIVE: Symbol on when either NFC or USB communication is active.

3. USB: Symbol on when USB port is connected to a PC. Please note battery is not required during
configuration.

4. LOG: Not used

5. Not used

6. BAR GRAPH: Indicates the state of the logger. The condition is dependent on the selected
logger mode, either Single or Rolling mode.

Single Mode (Log to the maximum number of logs then stop)
Start of Log Mid Log End of Log (alternating)

Rolling Mode ( L og t o th e m axi mum num ber of l ogs th e n as e ach n ew l og i s tak en the ol dest l og i s
discarded)
Start of Log Mid Log Rolled over Log (max bar toggles)

7. DEG: Degree symbol “°” used to indicate either °C or °F on the last digit.

8. DIGITS: Six-digit 14 s egment display with – sign, range 9999.9 to -9999.9. Advanced mode
offers two temperature-dependent 32-character message opt i o ns .

9. WARNING ICO N: This symbol wi ll to ggle o n and o ff to i ndic ate a warnin g. The warni ng sy mbol
will be active either when the sensor signal is out of range, not connected or when the battery is low.

MULTIFUNCTI O N ALE RT LE D

The alert LED normal state is off, on alert the LED will emit a intense
white light pulse every 5 seconds. The LED can be programmed to
pulse on any of the following combined events:
Mode Description
No events The LED never operates, extending battery life.
(Factory default setting)
Battery Alert on low battery detect.
Trip Alert when relay 1 trip is on.
Temperature In advanced mode only the alert LED can be made to
alert in any one of eight user-set temperature bands. Example, to
alert operator when temperature is outside a safe operating range.
The function of the alert LED can be further enhanced with the option

of displaying an alert message in advanced display mode.

NFC LOGGER INTERFACE

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 a 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/average readings. Logs can run to a fixed
number and stop or continually roll over, up to 5000 log points can be
recorded. The start of the log can be delayed up to one month.
Note: For larger logs the data may tak e ov er a m i nute to fully

download via the NFC interface.

USB LOGGER INTERFACE (connector inside housing)

The USB interface allows the instrument to communicate with a PC
running the USBLogLink software
The prime function of the interface is to read logged data from the
device using free software avail a bl e t o d ownload.
The software 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.
USBLogLink is available from the manufacturer or supplier.
