MKS Instruments 937B Vacuum Gauge Controller

class pymeasure.instruments.mksinst.mks937b.MKS937B(adapter, name='MKS 937B vacuum gauge controller', address=253, **kwargs)

Bases: MKSInstrument

MKS 937B vacuum gauge controller

Connection to the device is made through an RS232/RS485 serial connection.

The 937B gauge controller can connect up to 6 pressure measurement channels for gauges of various types which includes ionization gauges, Pirani and piezo gauges. Based on the pressure values of the gauges twelve setpoint relays can be energized when certain pressure values are reached. The assignment of the relays to measurement channels is fixed to have two relays for each pressure channel.

Parameters:

adapter – pyvisa resource name of the instrument or adapter instance
name (string) – The name of the instrument.
address – device address included in every message to the instrument (default=253)
kwargs – Any valid key-word argument for Instrument
