3. Maintenance
3.1 General Care of Instrument
This calibrator is a precision instrument. It has been constructed as
ruggedly as the service for which it is intended will permit. Every precaution
has been taken to prevent it from going out of adjustment when subjected
to vibration and shock. In view of this, the instrument should be handled
with care and protected against violent and sudden jolts.
This instrument is intended for use with clean, dry, non-corrosive gas only.
3.2 Air Filter
Replace air filter U28021 or U13422 at regular intervals depending on the
quality of the air supply and the frequency with which the calibrator is used.
To protect your precision instrument, routine filter change is necessary.
With daily use of the calibrator, change filter every month, with frequent
use, change every three months, and with occasional use, change filter
every year. Replacement filters are available from Transmation.
3.3 Regulator
The regulator can be replaced, if needed. Please consult Transmation for
the correct replacement of this part. Be sure to specify the range as
stamped on the bottom of the regulator.

supplied with the instrument, the charger connection is located on the DPC
face plate. The unit can be operated with the charger plugged in, the
batteries will charge while the unit is in use. In the event that the batteries
need to be replaced, standard NiCd AA batteries can be used. Non-
rechargeable batteries can also be used if desired. Contact the factory for
