Transducer Display
Model 9250
3.4 Display
The display is made up of two sections. In the main screen (“Measure Application”), the left two thirds
show the transducer channels that are configured for display, along with the pressure reading, units,
mode (absolute or gauge), channel label, an auto zero or tare button (if enabled) and any auxiliary
indications that have been chosen. The right one third of the screen has Application Icons (“Apps”) for
setting viewing options, sensor settings, communication settings, and a “Page Down” button [ ] that,
when pressed, shows a second and third page of icons for calibration, remote communication error
checking and a leak test application.
Buttons, Labels and Windows: The Model 9250 touchscreen has many buttons with relevant graphic
icons or text which, when pressed, will open a related window where changes can be made or
information viewed. Some of these buttons will toggle from one state to another, and others present
choices or display a numerical data entry screen. Text or icons that are displayed, but do not respond to
being touched, are called labels or windows. Operators will quickly become accustomed to the particular
characteristics of the frequently used buttons.
Main Screen: The main screen or “Measure Application” appears after power-up. This screen contains
the channel frames and settings button. It will remain as configured after a power cycle.
Transducer Channel Frame(s): The transducer channel frames (left 2/3 of the screen) contain
information specific to a channel. Up to three channels can be displayed at once, two are shown in the
picture above. The channel frames are color coded with channel A - green, channel B - blue, and
channel C - red. The delta channel is yellow. If only one channel is installed, a full frame will be displayed
in the color of the channel connected. The channel frame contains the pressure reading, units, and
mode (absolute or gauge) plus any auxiliary displays that have been chosen.
3.5 Chassis Assembly
The chassis assembly is the housing for the system. The system has no user-serviceable parts, and
therefore the chassis should not be opened except by qualified repair personnel at Mensor or certified
service locations for any reason.

Power Up
Apply power to the power connector on the rear of the instrument using the power adaptor included, and
switch the power switch on the front of the unit ON. The instrument will go through an initialization
process and system check. As soon as the system check is completed, the system will default to a
screen similar to the one shown in Section 5.1.2 - Display Screen Features. The main measurement
screen may be configured in many different ways but initially, it will be in a default configuration.
Subsequently, the unit will power up in the configuration that it was in when last powered off. Allow at
least 15 minutes of warmup before performing critical pressure measurements.

5 Local Operation and Setup
5.1 General Operation
This section describes the procedures for operating the Model 9250 from the front panel. Instructions for
operating the device remotely from an external computer are covered in Section 6, Remote Operation.
By following the procedures provided in these two sections and Section 9, Calibration, you can expect
your Model 9250 to be dependable for many years of useful service.
5.1.1
Setup Applications
Configuration of the Model 9250 is achieved by changing settings accessed through the Application
(“App”) buttons. Local operation is accomplished by observing the data presented in the display. The
appearance and functionality of the display can be changed by pressing the App button for the related
function. After an app has been chosen, a set of related parameters will appear on the left. After
choosing one of these parameters, a set of selections related to that parameter will appear on the right or
a data entry keypad. The desired selection or data can be entered here.
5.1.2
Display Screen Features
The screen shown below provides a brief description of the features shown on a two channel display
after initialization. The left two thirds of the display contains the area where information is displayed (in
this case the Measure Application) and the right one third contains the selection icons for each
application. Channels are color coded: Channel A is green, B is blue, and C is red. Color coding persists
throughout all channel-specific screens. A zero or tare button and auxiliary displays (auxiliary units, rate,
and peak) will appear in the Measure App if activated. All of the Model 9250 screen features are
described in more detail throughout this manual.
