6.6 Setting access (security) code
6.6.1 Security overview
The access (security) code prevents program and calibration settings from accidental
changes. The transmitter is shipped with the access (security) code disabled.
6.6.2 Entering the access (security) code
1. If calibration and program settings are protected with a security code, press PROG or
CAL on the infrared remote controller.
The ID screen appears.
2. Use the editing keys to enter the code. Press ENTER.
If the code is correct, the first sub-menu appears. If the security code is incorrect,
the process display reappears.
6.6.3 Retrieving a lost security code
1. If the security code has been forgotten, enter 555 at the ID prompt and press ENTER.
The transmitter displays the present code.
2. Press EXIT to return to the process display.
3. Press PROG or CAL.
The ID screen appears.
4. Use the editing keys to enter the security code. Then press ENTER.
The first sub-menu under the selected menu appears.
6.7 Using HOLD
6.7.1 HOLD overview
Activating HOLD keeps the transmitter output at the last value or sends the output to a
previously determined value. This is particularly useful when doing calibrations. During
calibrations, the sensor may be exposed to solutions that have concentrations outside the
normal range of the process. HOLD prevents false alarms and undesired operation as a
result of that reading. HOLD can be deactivated when the sensor is reinstalled in the
process stream and the readings have relatively stabilized.
