(Resolution) SUB MENU
The Series ISDP Controller is capable of displaying four digits of resolution.
However, at very low pressures the instability of the pressure may cause
fluctuations in the least significant digit causing the least significant digit to be of
little value.
Three digit resolution (
3DIG
) can only be active when there is at least one digit to
the right of a decimal.

DAMP
(Dampening) SUB MENU
Adjust from 1-16
Dampening stabilizes the display from instabilities due to things such as vibration
and excessive pressure fluctuations. The dampening setting adjusts the amount of
readings that are averaged for each display update. Adjust the dampening value
until the display reads a stable value for the application.

Maintenance
Upon final installation of the Series ISDP intrinsically Safe Differential Pressure
Transmitter, no routine maintenance is required. The Series ISDP is not field serviceable
and should not be returned if repair is needed (field repair should not be attempted and
may void warranty). Be sure to include a brief description of the problem plus any
relevant application notes. Contact customer service to receive a return goods
authorization number before shipping.
