No, limit values for Rel and Rct cannot be entered in the Metracell BT PRO. The limit values for Rel and Rct can only be entered in the BT PRO Manager software in Definitions → Block type. These are transferred to the Metracell BT PRO, but are not displayed there. If a limit value is exceeded during a measurement, an acoustic signal is correctly emitted and the background in the device for the resistance values Rel and Rct goes dark.
