1. INTRODUCTION
1.1 COMMON INTRODUCTION
1000TR is a new CE-approved series of transmitters from Elmacron AB. In the series, there are
instruments for pH, Redox%, Redox mV and temperature measurement.
1000TR is easy to program, calibrate and use.
The layout on the instrument is clear; a large display with four LED-segments, diode indication for the
menu and four large function keys. All settings are made through the function keys on the front panel.
When connecting an electrode to 1000TR-ORP% the display shows the actual value in the solution
measured.
1000TR-ORP% is provided with an isolated output 0/4 - 20 mA, proportional to the measured value,
for connection to, for example, a computer, printer or other recording equipment. When measuring is
interrupted, the output stays frozen at the last measured value.
1.2 PARTS & ACCESSORIES
1000TR is delivered without connection cables and electrodes.

2. INSTALLATION
2.1 CASING
The casing is made of die-cast polystyrol with a transparent front cover that is closed with a snaplock.
The connection terminals are located in a separate partition at the lower part of the transmitter.
At the bottom of the instrument there are four cable glands ( two 15,2 and two 18,6 ) for the electrical
connections.
The protection class is IP65.
2.2 MOUNTING
The instrument is designed for wall mounting. Be sure that the instrument is mounted at a non-
vibrating place.
1000TR is mounted vertically with two fastening screws (∅ 7) through the mounting brackets on the
instrument.
2.3 ELECTRICAL INSTALLATION
It is recommended that each instrument is provided with a separate power switch.
The electrode coax cable must be protected by a screen and may not be installed near power cables.
Avoid extension of cables.
The connection terminals are located in a separate space at the lower part of the transmitter.

2.3.1 Connection of the power supply
Connect the power supply to terminal 1 (earth), terminal 2 (zero) and terminal 3 (live).
2.3.2 Connection of the electrode
Electrode cabling is a critical part of the whole system.
• Use a low noise coax cable between the electrode and the input terminal on the controller.
• Low noise cables has, in general, a black semi-conductive sheath between the centrewire
insulation and the shield. Remove this sheath.
• Keep the cable away from power wires.
• Max recommended length of cable is 10 meters.
• Connect the shield ( reference ) of the coax cable to terminal 4 ( EL - ).
• Connect the centre ( metall ) of the coax cable to terminal 5 ( EL + ).
NOTE! When using electrode PtPK/G:
• connect the shield ( reference ) of the coax cable to terminal 5 ( ELECTR+ )
• connect the centre ( metal pin ) of the coax cable to terminal 4 ( ELECTR- )
2.3.3 Connection of a recorder
Connect the recorder to terminal 10 ( REC + ) and terminal 11 ( REC - ).
2.4 CHECK THE CONNECTIONS
Before the power supply is turned on; check that the connections are mechanical and electrical
correct.

3. FUNCTIONS
3.1 COMMON FUNCTIONS
All settings are made through the function keys on the front panel. The keys + and – are accelerating
in three steps when they are kept pressed.
Chosen function is indicated by a green diode in the menu, at alarm a red diode is activated at the
same time as the diode at the actual function activates. When pressing M you step down in the menu.
When calibration or setting mode is entered the output signal stays "frozen" at the latest value, until =
is pressed.

3.2.4 ALARM
When an error occurs in the measuring mode, the alarm diode activates at the same time as the error
code is shown on the display. At serious errors, the error code is flashing on the display.

4. PARAMETER SETTINGS
4.1 DEFAULT SETTINGS
When delivered, 1000TR have the following default settings.
Output 0 - 20 mA
Offset 5%
Slope 100% ( 20 °)
4.2 PARAMETER SETTINGS
All settings has to be confirmed with = to be saved. To leave the setting mode without saving the
settings: press M.
Before starting up the transmitter the following parameters has to be set: Temperature compensation
and output range.
Turn the power on.
4.2.1 Set the output signal
1. Interrupt the measuring by pressing + and – at the same time until the measuring is
interrupted and the diode at CAL.1 is activated.
2. Press M until the diode at OUTPUT. is activated. At the display: 0 - 20 .
3. Choose between 0 - 20 and 4 - 20 mA with +.
4. Press = to confirm. The diode at MEASURE is activated and the display shows Hold.
5. Press = to start the measurement.
4.3 CALIBRATION
It is recommended that the instrument is calibrated regularly, to get the highest possible accuracy in
the measuring. The instrument is preset for calibration at 5%.
During the calibration, the latest output signal stays "frozen".
See attachment "Calibration instructions" for calibration.
4.4 OPERATION
Measuring is started when the power supply is turned on. After an interruption off the measuring it can
be restarted by pressing = when the MEASURE diode is activated.
The display shows the actual value in the solution measured at the same time as the corresponding
mA-signal is sent to the output.
During the operation, the diode at MEASURE is activated.
