2.4.1 Assigning Set Points and Values The instrument has four relays that are assignable to any of the vacuum measurement channels. The default setting is thermocouple (or convection) Channel 1 is Channel 1 (CH 1), thermocouple (or convection) Channel 2 is Channel 2 (CH 2) and the ion sensor is Channel 3 (CH 3), if applicable. Set point SP 1 is relay 1, set point SP 2 is relay 2, and etc. The default assignments for each set point to each channel are SP 1 to Channel 1 and SP 2 to Channel 2 for all versions. For configurations with an ion sensor, SP 3 and SP 4 will be assigned to Ch ...

customer. Consult the appropriate section below to learn more about each sensor output. The MC300 will return to its normal operating mode after the fourth relay has been set up or 60 seconds have elapsed since the last button press. Changes are stored after the complete set up of an individual relay channel. These set up parameters are stored in non-volatile memory and are not lost during power outages. 2.5.1 2A Thermocouple Sensor The 2A Thermocouple sensor has two analog output formats.

The 4A Thermocouple Convection sensor has two standard analog output formats and possesses a third optional analog output format. The Traditional Output option mimics the output of the raw signal from the 4A sensor. The voltage can be converted to a pressure by using a linear interpolation table. To receive an MC300 with a 4A sensor analog output set to Traditional, the user must specify this change during ordering. The Linear Output option provides a linear signal from .001 Torr to 1 Torr. The voltage can be converted to a pressure via an equation. The Linear Output is included in stan ...

calibration of new units is unnecessary. However, with extended use, sensors characteristics may change and the user may wish to calibrate sensors to return the unit to maximum accuracy. Users may also wish to calibrate replacement sensors. Please see the below sections for more information on calibrating each specific sensor. The correct calibration of each sensor includes pumping down to one order of magnitude of pressure below the desired calibration point, using a controlled, dry nitrogen leak to increase the p ...
