1 Introduction
This document applies to products with part number:
PT G25 400
The part number (No.) can be found on the product nameplate.
This Operating Manual is based on the firmware version V04.3. Previous firmware
versions may not have the complete functionality described in this Operating In-
structions.
If the device does not work as described, please check if it is equipped with this
firmware version. You can find the firmware version number of your device in the
[Detail] > [Info] > [MC-Board] menu (→«Info», 29).
We reserve the right to make technical changes without prior notice.
There is a type label attached to one side of the device. In all communication with
Pfeiffer Vacuum, please state the information on the type label.
The Ionization Gauge Controller IMG 400 is a versatile microprocessor controlled
ionization gauge controller for pressure measurements in the range
1×10-13 … 1.1×103hPa.
The concept and design of the controller allow for a reliable and complete inte-
gration in complex process control systems.
The IMG 400 can handle four measuring systems simultaneously. An optional
interface may be used for complete remote control of the device.
In the following, the Ionization Gauge Controller IMG 400 will be referred to as
«IMG 400».

The measuring speed that can be achieved with IMR gauges depend on the ion
current to be measured and the selected resolution (details →"Current Measuring
Amplifier (Amplifier)", 63).
The measuring rate of the gauges is 20 s-1 over the entire measuring range.
The filter time constants depend on the measuring rate. The actual measurement
is the average of the last n measurements. The filter settings are defined as fol-
lows:
Slow: n = 50
Fast: n = 5
Normal: n = 15

1) All gauges of the same type use the same identification resistor. The valid measuring range must be
configured by the user (→"Measuring Ranges", 8).
Both gauges are identified automatically by the software. If no gauge is
found on channel 1 or 2, the controller assumes that a Bayard-Alpert
gauge is connected to channel 1. That way the system is still operable.
