7.2.2 Calibration Routine
Before starting temperature calibration you need:
• Thermocouple simulator capable of providing accurate set points of
20°C and 400°C.
• Suitable connector plug so that you can connect your simulator to the
appropriate zones without any heater zones being connected. If in
doubt, consult the loom wiring diagram to check for heater and
thermocouple pin connections.
7.2.3 Calibration Sequence
1. Connect the simulator to the normal thermocouple inputs for both zones
on the module being calibrated.
2. Choose [Cal] and [ ] to start the calibration routine.
3. The screen asks for a 20°C source – set your thermocouple simulator to
20°C.
4. The screen timer counts down as it sets the low range setting.
5. The screen asks for 400°C source – set your thermocouple simulator to
400°C.
6. The screen timer counts down as it sets the high range setting.
7. The screen informs you that the calibration has completed.
8. Remove the thermocouple simulator and temporary connector.
