Dear Customer,
Thank you for reaching out to us through our forum! I can assist you with general information regarding the pin-outs and current drive. However, I want to highlight that using a traditional current source and voltage input to obtain usable measurements from the FP probe may not be feasible. The F41/F71 utilizes a current-spinning technique to eliminate offset, and I anticipate that the offset you would measure with your setup would be significantly large. Additionally, without a calibration reference, the probe measurements would lack meaningful interpretation.
If you still wish to proceed with connecting the probe to your equipment, kindly send me the model number of your probe via email at support@lakeshore.com. I will then provide you with the appropriate pin-out details for the probe series. The current drive for the probe is 1mA.
Greetings, Ogi K.

Dear shmah1:
There are several reasons that will trip this error. Please check for the following and send me an email to support@lakeshore.com with your findings:
1. Model and serial number of your controller 2. Do you have a valid sensor reading for the sensor that is configured for the control loop (or is the sensor showing an error such as S.OVER, T.OVER)? 3. Does this error occur in all or just specific heater output ranges? 4. Does your error pop up immediately after you turn the heater on or does it take some time to trip?
Thank you, Ogi K.

Hi again - I confirm that this is used to wire the high temperature stage access to heaters. Greetings, Ogi K.

Hello and thank you for reaching out to us!
Can you please send your contact information and the serial number of TTPX (or it's temperature controller) to support@lakeshore.com so I can review the original order and what this connector was setup for?
Thank you, Ogi K.

Dear Andreas,
I am sorry for the delayed response. There may be a slight, very minimal delay, but we have not measured and specified it nor do we understand if the delay remains the same throughout the various measurements (AC or DC). If you're observing a delay in measurement, it could also be due to the settling time of the measurement signal. The entire measurement stage is AC-coupled to get rid of DC offsets.
Greetings, Ogi K.

Hello and thanks for reaching out!
We've seen similar before and a reset to factory defaults should fix the issue.
To reset the instrument to the factory defaults: 1. Tap the Settings menu (top left corner of the screen). 2. Tap System settings. 3. Tap Reset, then tap Reset instrumentation settings. 4. A confirmation message will appear. Tap Reset to confirm the action.
If you continue having issues, please contact us at support@lakeshore.com for further troubleshooting.
Greetings, Ogi K.

Hello Jeff,
The Model 218 has two input connector plugs in the back that mate with a DB-25 connector that you will have to purchase if you don't have an extra one. Please refer to the user manual section 3.3.2.1 for the pin-out as you will need it when terminating the wires.
As this is a platinum sensor, a 4-lead connection should be used all the way from the sensor to the Model 218. We have cryogenic 4-lead and 4-lead-twisted pairs that both will work great. Lastly, we recommend soldering the wires to the connector to ensure a good and reliable termination.
Greetings, Ogi K.

Dear Franziska,
This sounds like you have your manual output turned on to a percentage higher than 0%. The manual output then acts like an offset when used in PID control mode. Please press the "Manual Out" button and ensure it is set to 0%. This should take care of the "higher temperature than the setpoint" problem and may also take care of your tuning issue. If it doesn't please let us know. A brief description of your setup would be useful too.
Greetings, Ogi K.

Greetings!
Is your Cernox 1030 sensor calibrated or was it purchased uncalibrated? If the sensor is uncalibrated, you will either need to create your own calibration curve or send it to us for calibration. Since Cernox sensors do not have a standard curve such as diode and platinum sensors, you will need to load the sensor's curve into the Model 211 using a serial interface and our curve handler software. Then you will be able to select the curve for the sensor and configure the 211 properly.
Best Regards, Ogi K.

Hi! It is possible that the quench just corrupted the memory in the unit and a firmware re-load might do the fix. If it doesn't help, the unit will have to be returned to the factory for repair. Firmware Updater: www.lakeshore.com/products/firmware-updaterPlease try the firmware update if possible and send us an email to support@lakeshore.com in case you need further assistance. Also send us the serial number of the unit so we can get started on the RMA paperwork. Greetings, Ogi K.

Hi! I believe we also corresponded over email and solved that issue by using our legacy version of the curve handler. This version can be downloaded here: Install Curve HandlerGreetings, Ogi K.

Hello Michael,
Sorry to hear that you're having this issue. The firmware would fix this problem in case it happens randomly rather than repeated. Your case doesn't appear to be this.
Here are a few things I would suggest trying: 1. Unplug the heater in the back of the instrument and measure the resistance across the banana plug of the heater wire. 2. Does the heater stop working (and you get this error) at a certain temperature? If yes, it could be a failing heater or solder joint that becomes noticeable at a certain temperature(s) due to thermal expansion/contraction. 3. Try other heater ranges and see if they are failing as well
I suggest emailing us the results you find of the suggestions above to support@lakeshore.com so we can further troubleshoot if necessary.
Greetings, Ogi K.

Dear Jacob,
In the 3726 scanner, the channels that are not being read are shorted to ground. We did that to eliminate noise, and hence heating, into the environment. Your assumption is most likely correct (that it is a noise issue). Now that you now about the unused channels, I hope it will enable you to debug your issue. However, if you end up having more questions, please let us know.
Greetings, Ogi K.
