PRODUCT INTRODUCTION

OVERVIEW
The Accu-Cal Platinum Digital Ultra-
Precision Test Gauge combines the high
accuracy of digital electronics with the
convenience and ease of use of an analog
test gauge. Accurate to ±0.04% of reading
plus .01% full scale FS, the Accu-Cal
Platinum can be used as a calibration ref-
erence, or in any application where high
accuracy pressure measurement is
required.
Many user configurable functions have
been designed into the Accu-Cal Platinum
including sampling rate, TARE, damping,
auto shut off, and Max/Min. Once the
gauge is configured, settings can be
locked and password protected to prevent
unauthorized changes to configuration.
UNPACKING
Check to see that your Accu-Cal Platinum
has arrived intact. Batteries are factory
installed unless you have purchased the
optional 24V powered version, in which
case batteries are not supplied or
installed. Save the packing materials at
least until you have verified that there is
no concealed damage.

PRODUCT USAGE WARNINGS/CAUTIONS
Should the Accu-Cal Platinum be exposed
to overpressure or sudden physical shock
(i.e. being dropped) it should be examined
for any damage that may cause a safety
concern. If in doubt please return unit for
evaluation to 3D Instruments. Please refer
to the Warranty section on page 19 for
company contact information.
CAUTION
To avoid possible damage to the gauge
or to equipment under test:
• If the LCD displays "OL", then the pres-
sure range limit has been exceeded and
the pressure source must immediately
be removed from the Accu-Cal Platinum
to prevent damage to the pressure
transducer.
• There is no "OL" indicator for vacuum
measurement on any of the pressure
ranges. Generally, at room temperature,
no damage will result to any of the posi-
tive pressure sensors should they be
inadvertently be exposed to vacuum. In
applications where the temperature is
very high or very low, the sensor on the
30 psig range will be damaged by vacu-
ums in excess of -5 psig.
• Maximum torque allowed is 13,5 Nm =
10 ftlbs. NEVER exceed the allowable
torque.

INSTALLATION

Prior to installing the gage into a process
connection, please ensure all pressure is
vented from the system. Ensure that you
use proper fittings to mate with the gauge.
Failure to utilize proper fittings will result in
leaks. Never attempt to tighten the unit by
turning the gauge housing by hand. This
may result in permanent damage to this
gauge.
