Contact with harsh solvents and chemicals to any plastic parts of the HPM 4/6 Vacuum Gauge can damage the unit and may void the warranty.

Instrument repair should only be performed by Teledyne Hastings service technicians.

Disconnecting gauge tube by pulling on the cable may result in damage to the octal socket and/or cable.

Electromagnetic interferences (EMI) in the frequency range 80MHtz to 1000MHz at intensity levels of 3V/m may cause the HPM-4/6 unit to display up to a 21% deviation from the correct reading.
