Warnings
◆Do not combine with another pressure source where pressure is being generated by both sources at the same
time.
◆Do not apply pressures greater than the maximum working pressure.
◆Not for use in flammable, high humidity, or dusty environments.
◆Do not expose the battery to fire.
◆Charge the battery only using the Additel adapter. Please follow proper recycling procedures when discarding the
battery.

2
General safety
◆Do not shake, drop or bump the calibrator while in use.
◆If condensation has occurred, thoroughly dry out the 761A before startup.
◆Connecting the REF port to the reference port of unit under test (UUT) with a small differential
pressure range might result in control problems over time as the environmental temperature
changes. It is recommend to connect the REF port of the calibrator to the low pressure port of the
UUT to resolve control issues.
◆The vent port should not face the operator during venting.
◆Do not apply more than 30V between any two electrical jacks (except for voltage measurement
jacks)
◆Do not use any adapter other than Additel power adapter designed for the ADT761A. Charge the
battery as soon as the battery symbol indicates.
◆If the calibrator is not working properly, turn it off, remove the battery and contactAdditel.
◆Do not remove the battery while it is charging or when the calibrator is in use.
◆Before turning off the calibrator, make sure the system pressure is reduced to the atmosphere
pressure.
