ArEA , DIA , XDIM and YDIM SUB ENUS
These SUB MENUS become accessible if the instrument is set for flow. When measuring
flow, the area of the duct must be specified. Tables 3 and 4 show the input range vs
maximum flow and duct size. For a rectangular duct the maximum size is specified in
square feet or meters. For a circular duct the maximum size is specified as the diameter.
X, Y and circular dimensions are entered in feet with 0.01 foot resolution for
FLOr = LO and
0.1 foot resolution for
FLOr = HI , or entered in millimeters with 1 millimeter resolution.
ArEA - Area, select CIR for a circular duct or RECT for a rectangular duct. f a
circular duct is selected, the
DIA SUB MENU will be activated. f a rectangular duct is
selected, the
XDIM and YDIM SUB MENUS will be activated.
DIA - Diameter, enter the diameter of a duct
XDIM - Enter the “X” dimension of a duct
YDIM - Enter the “Y” dimension of a duct
d.S (Display) AIN ENU
PEAK - Peak value rESO - Resolution
VALy - Valley value Pd.S - Process display
ZERO - Zero DAMP - Dampening level
PEAK (Peak) SUB ENU
The Peak feature stores the highest pressure reading the instrument has measured
since the last reset or power up. At power up
PEAK is reset to the present
pressure reading. To manually reset the
PEAK value, press the ENTER key while in
the
PEAK SUB MENU.
VALy (Valley) SUB ENU
The valley feature stores the lowest pressure reading the instrument has measured
since the last reset or power up. At power up
VALy is reset to the present
pressure reading. To manually reset the
VALy value, press the ENTER key while in
the
VALy SUB MENU.

rESO (Resolution) SUB ENU
The Series SDP 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.
3DIG - Set display for 3 digit resolution
4DIG - Set display for 4 digit resolution
Pd.S (Process Display) SUB ENU
STD - Display reads pressure, velocity, or flow values
PCT - Display reads % of full scale value
When the display is reading percent,
PCT is displayed in the upper right of the
display. The percent display is only available in pressure operation.
DAMP (Dampening) SUB ENU
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.
AdU (Advanced) AIN ENU
POL - Process output low
POH - Process output high
ZERO - Zero calibration
SPAN - Span calibration
POL and POH (Process Output Low and High) SUB ENUS
This feature is used in pressure operation only.
Process output low and high are used to scale the 4-20 mA output. Set
POL to the
desired display reading for 4mA output, and set
POH to the desired display
reading for 20 mA output.
POH must be higher than POL . POL may be adjusted 2%
BELOW minimum scale up to
POH . POH may be adjusted from POL to 2% ABOVE
maximum scale.
www. .com [e-mail]1.800.561.8187

ZERO and SPAN (Calibration of Zero and Span) SUB ENUS
The lower display reads CAL in this mode.
ZERO Calibration
NOTE: For accurate calibration, DO NOT apply any pressure when performing
this function.
With the display reading
ZERO , press the ENTER key. The upper display will blink.
Press ENTER again to complete the zeroing of the instrument or press the
MENU
key to cancel.
SPAN Calibration
With the display set to SPAN , apply full scale pressure to the unit. Press the ENTER
key. The upper display will blink. Press ENTER again to complete the calibration or
press the
MENU key to cancel.
aintenance
Upon final installation of the Series SDP intrinsically Safe Differential Pressure
Transmitter, no routine maintenance is required. The Series SDP 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.
