Zero Adjustment Limits:

Zero can be fully elevated or suppressed, within

the lower and upper range limits of the capsule.

External Zero Adjustment:

External zero is continuously adjustable with

0.01% incremental resolution of span. Re-range

can be done locally using the digital indicator

with range-setting switch.

Integral Indicator (LCD display):

5-digit numerical display, 6-digit unit display and

bar graph.

The indicator is congurable to display one

or up to three of the following variables

periodically.; Differential pressure, static

pressure, temperature.
