Crystal Engineering IS33 Dual Sensor Digital Pressure Calibrator

0 to 110% of Range:

± (0.05% of Reading + Floor Term)

Includes all effects of linearity, hysteresis, repeatability, temperature, and stability for one year.

All models indicate vacuum, but vacuum specification applies to 16 PSI, 36 PSI, and 300PSI models only.

Not recommended for continuous use below -14.5 PSI.
Refer to XP2i-DP data sheet for gauges that are intended for continuous high vacuum use.

Floor Term:

0.005% of FS or display resolution, whichever is greater

Vacuum:

± (0.25% of Reading + Vacuum Floor Term)

Vacuum Floor Term:

0.004 PSI for 16 and 36 PSI
0.01 PSI for 300 PSI

Accuracy:

± (0.025% of Reading + 0.001 mA)

Includes all effects of linearity, hysteresis, repeatability, temperature, and stability for one year.

Range:

0 to 55 mA

mA can be displayed as a percentage, where 0 to 100% corresponds to either 4 - 20 mA or 10 - 50 mA.

Resolution:

0.001 mA

Jacks are compatible with safety sheathed banana plugs.

Connection:

4 mm jacks, 19 mm (0.75") spacing

Temperature Range:

0 to 50°C (32 to 122°F)

Non-condensing. No change in accuracy over operating temperature range. Gauge must be zeroed to achieve rated specification.

Screen:

2 lines of up to 6 digits,
5 mm (0.2") high

LCD readable in sunlight.

Display Rate:

2 rdgs/sec (adjustable to 1, 3, or 3.7 rdgs/sec)

Changes to reading rate requires free ConFigM30 software.

1 x 9V:

90 hours, typical

Uses 1 alkaline 9V battery. Use USB interface reduces operating time.

Do not use AC power supply in hazardous locations.

Digital Interface:

micro-USB

Free Labview drivers and programming instructions available online.

Do not use USB in hazardous locations.
