The Calibrator makes 5-digit pressure measurements in
the units shown below:
• Psi
• inH2O at 4 °C
• inH2O at 20 °C
• kPa
• cmH2O at 4 °C
• cmH2O at 20 °C
• bar
• mbar
• kg/cm2
• inHg
• mmHg
For pressure modules, full-scale readings for all pressure
ranges can be made in:
• Psi
• kPa
• inHg
To avoid display overflow, full scale readings are limited
to 1000 psi in cmH
2
O, mbar, and mmHg units, and
3000 psi in inH
2
O units. Pressures of at least 15 psi must
be measured for meaningful readings in bar and kg/cm
2
units.
Safety Information
A Warning identifies conditions and actions that pose
hazard(s) to the user; a Caution identifies conditions and
actions that may damage the Calibrator or the equipment
under test. Symbols used in this manual and on the
Calibrator are listed in Table 1.
XWWarning
To avoid possible electric shock or personal
injury:
• Use the Calibrator only as specified in
this manual, otherwise the protection
provided by the Calibrator may be
impaired.
• Never apply more than 30 V, including
transients, between the mA terminals, or
between either of the mA terminals and
earth ground.
• The Calibrator is rated for CAT I
measurement only. Do not use the
Calibrator to make measurements in a
CAT II, CAT III, or CAT IV environments.
CAT I equipment is designed to protect
against transient from high-voltage, low-
energy sources, such as electronic
circuits or a copy machine
• Remove the test leads from the
Calibrator before opening the battery
door.
