The DPC-501 is a user-friendly, accurate and compact solution for pressure comparison calibrations. The electronic pressure calibrator DPC-501
is used for high-precision calibration of pressure instruments, e.g. pressure gauges, pressure transmitter, digital manometer, pressure switches,
overpressure protection valves, etc.
The DPC-501 measures pressure, voltage and current and supplies
24 VDC as source for transmitters. Calibration procedures can be predefined and used for calibrations on site. The DPC-501 is featured with
USB and RS232 interfaces and is powered by a Lithium-Ion battery
(rechargeable without memory-effect).
The built-in reference sensor is changeable, whereby several pressure
ranges can be covered with one DPC-501 unit. All standard pressure
ranges between vacuum and 1000 bar (14,500 psi) are available as well
as vacuum and absolute pressure ranges.
In “measuring” operation, the DPC-501 displays simultaneous:

• Reference pressure
• Output of unit under test
• Deviation (in selected pressure unit)
• Deviation (in % of full scale or of reading of unit under test)
This means that it is very easy to check if the unit under test is within it’s
specified accuracy class.

JOFRACAL CALIBRATION SOFTWARE
JOFRACAL calibration software ensures easy calibration
of RTD´s, thermocouples, transmitters, thermoswitches,
pressure gauges and pressure switches. JOFRACAL can
be used with all JOFRA calibration instruments. When
used with ASM-800 signal multi scanner, JOFRACAL can
perform a simultaneous semi automatic calibration on up
to 24 pressure and/or temperature devices under test in
any combination.
JOFRACAL software controls the complete calibration
procedure, stores the results and provides a calibration
audit trail through hard-copy certificates. All calibration
data are stored for each sensor to monitor drift and optimise recalibration intervals. A scheduler feature allows
planning of future calibrations.

FUNCTIONAL SPECIFICATIONS
Pressure range
The DPC-501 does all it´s reference measurements via the
DPC-J reference sensors. It is therefore always delivered
with one user-specified DPC-J reference sensor.
