= Datataking Limits

- when you reach this [limits](<https://www.fact-project.org/logbook/misc.php?page=limits> "Datataking Limits") stop datataking
- switch off voltage
 - BIAS_CONTROL/SET_ZERO_VOLTAGE
- wait a few minutes, so that the camera can cool down
- track another region and try again datataking (you can first test which currents you will get, by following steps):
 - FEEDBACK/START_CURRENT_CONTROL 0.0
 - BIAS_CONTROL/SET_GLOBAL_DAC 1
 - this will ramp up the voltage, so that you can check the currents

- if it is raining
 - switch off voltage
 - close lid
 - park telescope
