Omega manual FOB100 Single Channell

2)Serial communication status ligght: These indicators are directly connected to the Tx and Rx lines of the RS-232 interface. This is useful to coonfirm a good communication link with your PC when the FOB100-SOFT software package is used.

3)RS-232 communication interfaace: This port is used to configure and extract information for the instrument. This DB-9 connector usees the same pin-out as a COM port on a PC computerr. Use a simple pin- to-pin wired cable (not a null modem cable) to connect to a computer. See below for a coomplete description of the serial commands that are availlable.

4)2 x 16 Display: Under normal usse, the display will show the temperature readings for the user selected channels; the temperatures are displayed in either oC or oF. However, when the FNCT key is used, information is displayed to guide the user in making the selections (see item 5 below).

5)FNCT and SET keys: When the FNCT key is not activated; the display will show the teemperatures for the requested channels. The FNCT key allows the user to scroll through the menu items. All settings are kept in permanent memory, until changed aggain by the user, using either the keypad or a RS232 command.

This key allows users to scroll through the different options.

This key allows users to browsse from field to another, for options that have many fields.

This key allows users to set a value to the selected field.

The description of each of the menu items is:

1- Sampling rate: Adjust the reesolution of the display. In Fast mode, the instrumen t focuses on faster response time. In Slow mode, the focus is on higher resolution; this is achieved byy averaging the last 4 temperature measurements, which tends to reduce the noise, but to incrrease the effective response time. In Slow mode, the display shows gives temperatures in hundredthhs of degrees, while in Fast mode the display is inn tenths of degrees.

2- Ch Enable Scan: Enable or disable the reading of a channel. Channels that aree turned off are not read, thus allowing the “on” channels to be read faster.

3- Temp. Unit: Enable users to change the temperature unit of the instrument. Thhe thermometer will continue to display temperatures using the newly selected unit.

6)Power switch. Make sure the FOOB100 power supply module is connected and powerred. At power on, a series of messages are displayed (acctual information may differ):

Then temperatures should then bee displayed, assuming they are correctly connected, and so forth. If temperatures are unreadable, ------will be displayed.

7)Power status light.

8)Sensor connector(s): These are ST type connectors, mating to each of the 4 optical temperature sensors. If you need to extend a seensor fiber, you should use optional patch cords that are available from Omega. For thermometers that have 1 or 2 channel(s), only 1 or 2 sensor connectors are used.

1This is the calibration date (format YY/MM/DD).
