STARTUP and OPERATION
4.7 Viewing Data via the Pocket PC Web Browser
The Pocket PC Web Browser menu can be accessed via the pocket pc main menu. In
the top upper left hand corner of the menu the name of the unit will be displayed (ucem
XXXX). Point on this name. A drop down menu will appear. Point on Internet Explorer.
A sign on page will then be displayed. User name and password will be the identical as
the normal names used on the administration settings. Very importantly the Web
Browser function allows the user to access all data (calibrations, alarms, emission data
logs, diagnostics) internally stored in the MicroCEM.
The Web Browser will show the following screens/options for the user. Note that these
screens are updated once every 10 seconds unless the refresh bottom is pressed:
Real Time: This screen is identical to the main menu screen normally shown on the
pocket pc.
Emissions: This screen will enable the user to view all internal emission data logs
stored in the MicroCEM. User can choose between 1, 15, 1hr or 24 hour periods. A
designated time frame or most recent data can be choses. The report generator will
display data in a chart type format showing each gas value and associated time along
with data flags. The function is very helpful in very historical data or performing trouble
shooting.
Alarms: This screen will allow the user to display all alarms and time frames. User may
choose time frames or most recent alarms.
Cal: Display of all calibrations with results can be viewed from this page.
User Config: This file contains user selectable files that are typically input at startup
and never changed. See section 4.4 for details on descriptions. Note that reboot of the
MicroCEM may be necessary for system to accept changed for several items in this file.
Factory Config: Do not access this file unless a certified Rosemount technician is
present. Changes to this file may adversely affect or destroy the unit. Changes
made to this file without the written consent of the MicroCEM Product Manager will void
the warranty.
Download: User can easily download all data log files (Emissions, Alarms, Calibrations)
stored in the MicroCEM. This is typically used when user is accessing the MicroCEM via
a separate laptop or tabletop computer. See next section.
Temp Diag: Temperature diagnostics is a very important tool for diagnosing existing
problems or potential issues/problems with the MicroCEM.
The following parameters will be shown: Temperature Parameter, Temp Setting, Actual
Temp and Integral %.
*Zone Temperature: Zone temperature is typically set to 47 degrees C. This is the
temperature of the MicroCEM taken from the detector section thermocouple that is
located behind the pressure gauge. This thermocouple is always used for systems with
no CO. For systems with CO a thermocouple is located on the CO assy detector. The
MicroCEM will typically control temperature to within +/- 1 degree C. Depending upon
the outside ambient temperature the % on time can be from 0 to 100% on. If a negative
value is shown in the integral then cooling is in process. Variations greater than 1
degree C will lead to gas measurement drifting.
*PMD Temp: This is the Temperature of the chassis of the MicroCEM. Thermocouple is
located in the PMD detector. Temperature is typically within 2 degrees C. of the zone. If
the temperature drifts greater than this. Upon first turn on of the MicroCEM this temp
can be monitored. Once this temp is within 2 degrees C of the Zone then the unit is
ready for accurate measurements. Temperature above the 2 degree variance of the
