High Temperature Stage Support
This section contains support specific to high temperature stages, including TS1000, TS1200, TS1500, TS1400XY, CCR1000 and HS1500. If your question isn’t listed here it could be covered under the ‘General Stage Support’ page.
Testing sensor and heater connections on a high temperature stage
CAUTION: Make sure that the heater has cooled to ambient temperature, power off the controller and remove the stage lead and thermocouple connection cable from the back of the controller before performing this test.
In order to determine whether your heater or sensor is working correctly, you can measure the resistance of the pins as shown in the picture below.
(Resistance values shown are approximate)
The current into the heater exceeds a pre-set level
The TS1400XY stage is protected by the system controller using a solid-state cut-out. If for any reason the current into the heater exceeds a pre-set level, the power will be automatically turned off and the message 'PWR SURGE' will be displayed on the programmer. This could happen, for example if a cold sample is introduced at high temperatures or if a gas flow is too high. To reset the system controller, allow the stage to cool and then press any key.
