Disclosed is an oxidation process to produce a crude carboxylic acid product carboxylic acid product. The display unit displays information including information of time. A signal is transmitted to the virtual machine to enter an offline state, wherein the offline states comprises a transfer of at least one of a central processing unit state and a memory state, and wherein the virtual machine is configured to halt a processing of the UDP packets in response to receiving the signal. The scaled termination voltage and the scaled compensation voltage operate on the differential termination and attenuation network to optimize the dynamic range of a differential amplifier connected to the first and second attenuator outputs.
