Page 10: Safety
Once the emission is switched on, the active voltages at the two sockets of the IMG 400 are danger- ous to touch, even if only one measurement system is connected. In case of error during operation with the IMR 420 and IMR 430 gauges, a dangerous voltage is active at the measurement cable con- nection. - Page 11 Once the emission is switched on, the active voltages at the two sockets of the IMG 400 are danger- ous to touch, even if only one measurement system is connected. In case of error during operation with the IMR 420 and IMR 430 gauges, a dangerous voltage is active at the measurement cable con- nection.

Page 19: Connecting Bakeable Measurement Cable To Gauge Flange
The distance between the flange of the built-in measurement system and the connector guide is greater in the case of the built-in measurement system for the IMR 420 gauges. This is why 3 spacers are inserted between the flange of the built-in measurement and the connector guide. -

Page 21: Operation
Operation 6 Operation Halogen gases in the process If halogen gases such as fluorine, chlorine, bromine, and iodine or their compounds occur, the yttrium oxide layer of the iridium cathode will be removed within a very short time. As a result, the cathodes will burn out. Incorrect measurements due to stray currents Moisture on the insulators, e.g., condensate, can lead to incorrect measurements due to stray currents. -
