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-mV the display shows the actual mV-value in the solution
measured.
1000TR-mV is provided with an isolated output 0/4 - 20 mA, proportional to the mV-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.

These solutions have limited durability and should be used immediately after preparation.
Use the solution that is closest to 0 mV as offset-solution.
1. Interrupt the measuring by pressing +and –at the same time.
2. Clean the electrode in diluted hydrochloric acid. Rinse with water and weep it clean with
soft paper.
3. The instrument automatically steps down to CAL. 1 ( calibration point 1). Pre-set “zero-
point” is at 0 mV, if another offset value is desired it can be set with +and -. Press = to
confirm.
4. Put the electrode in buffer 1. Press = to start. Wait until the value at the display has
stabilised. Use +and –to set the correct value. Press =to save the calibration.
If the measured value differs more than ± 100 mV* from the pre-set buffer value, calibration can
not be performed. When pressing = a message is shown, ( see chapter 6 ). Locate and correct
the error and try again. Press M to interrupt the calibration at this value and continue with next
calibration point.
5. The instrument automatically steps to CAL. 2 (calibration point 2).
At calibration point 2, the instrument is calibrated at a high-buffer value ( > 0 mV ). If no calibration at
point 2 is desired, the point can be ignored by pressing Muntil the diode at CAL.3 is activated.
6. The pre-set value on buffer 2 is 1000 mV, if another value is desired it can be set with +
and -.
7. Rinse the electrode membrane carefully with water.
8. Put the electrode in buffer 2. Press = to start. Wait until the value at the display has
stabilised. Use +and –to set the correct value. Press =to save the calibration. If the slope
differs more than ±10%* the calibration is not accepted and the value can not be adjusted.
If the slope differs more than ±10%,* the alarm diode is activated and the calibration can not be
done, when pressing =an error message is shown, (see chapter 6). Accept the error by
pressing =. Locate and correct the error and try again. Press M to interrupt the calibration.
9. The instrument automatically steps to CAL. 3 (calibration point 3).
At calibration point 3, the instrument is calibrated at a low-buffer value (< 0 mV ). If no calibration at
point 3 is desired, the point can be ignored by pressing M.
10. The pre-set value on buffer 3 is -1000 mV, if another offset value is desired it can be set
with +and -.
11. Rinse the electrode membrane carefully with water.
12. Put the electrode in buffer 3. Press = to start. Wait until the value at the display has
stabilised. Use +and –to set the correct value. Press =to save the calibration. If the slope
differs more than ±10%* the calibration is not accepted and the value can not be adjusted.
If the slope differs more than ±10%,* the alarm diode is activated and the calibration can not be
done, when pressing =an error message is shown, (see chapter 6). Accept the error by
pressing =. Locate and correct the error and try again. Press M to interrupt the calibration.
13. Step to MEASURE with M.
14. Rinse the electrode membrane carefully with water.

16. The instrument is now ready for measuring. Press Mto start.
*The accepted range is calculated in relation to the distance from the offset value.
Example:
Offset ( zero point )
0mV
Calibration point 1
600 mV
Calibration point 2
-
600 mV
Accepted slope is ±10% from ideal slope. The deviation is calculated according to:
∆mV600 = 600 - 0 = 600, which gives max deviation = ±10 % of 600 = ±60 mV.
∆mV-600 = (-600) - 0 = (-600), which gives max deviation = ±10 % of (-600) = ±60 mV.
The accepted intervals in the example: calibration point 1 = 540 - 660 mV
calibration point 2 = (-660) - (-540) mV
Accepted limits for the offset value is (-100) - 100 mV
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
