Hello,
First time posting on this forum. I have a lakeshore 336 that I want to use for temperature monitoring and control.
I want to use one of the outputs in "high" mode, full power. As both outputs work correctly in "low" and "mid" ranges, when it is in "high" range the resistivity drops to close to zero, instead of showing the resistivity of my heater.
Is their a parameter I need to change somewhere? Or is it an hardware issue and I need to send my LS336 to repair?
Thank you for your help! |

In order to assist you I need to know what the heater resistance is. The High heater range on the Model 336 can work with heaters that have a resistance between 5 and 500 Ohms. If your heater is less than 5 ohms, you will see the heater short error once the output reaches 30%. On the hi end, anything greater than 500 ohms will produce a heater Open error.
If your heater resistance is between 5 and 500 ohms and you are seeing the error, the Model 336 will need to be sent back to the factory for a repair. If that is the case, please contact us at support@lakeshore.com and provide teh serial number of the 336 as well as your contact information.
