OM-60-TT SERVICE LOGGER

TWO TEMPERATURE SENSORS

WITH

The OM-60-TT is a Service Logger with two temperature sensors. The sensors are field interchangeable and are available as part # OM-60-MOD-TT. The OM60-MOD-TT option consists of two temperature sensors, an interface box and a cable which connects to the Service Logger. The OM-60-TT allows for two independent temperature measurements.

Each temperature sensor is enclosed with a 4 inch stainless steel jacket which may be immersed in any solid o r li q u i d w h i ch i s co mpatible with 300 series stainless steel. Refer to the product specifications for the environmental limits of the temperature sensors. The OM-60-MOD-TT series temperature sensors are interchange-able and replacement sensors are available. Each temperature sensor is supplied with a 6 foot long cable

Immersion of the entire sensor body and cable, and/or cutting or splicing of any of the OM-60-MOD-TT cables by the user is not recommended and will void th e sensor warranty.

GETTING STARTED

Connect the interface cable from the interface box to the Service Logger. Plug each temperature sensor into the interface unit. Note that the interface box is labeled to indicate which temperature sensor corresponds to Temp 1 and which sensor corresponds to Temp 2. If portable use or battery backup is desired, place a fresh 9V alkaline battery into the Service Logger. Any other type of battery will result in unsatisfactory performance and may cause damage to the instrument. Plug in the power ad a p ter i f a 110 (220) Vo lt o u tlet i s a ccessi b le.

Press the "ON" button on the front panel. The display will show the instrument name. If no display is visible, or if the display is all black, adjust the display control until the lettering is visible.

If no adapter is connected, or if the adapter has become defective the display will show this message. The Service Logger will recognize when an interface unit is plugged in and automatically set up the correct menus and displays for that interface.

CHANGING SETTINGS

Every function of the Service Logger can be set through a series of menus. Settings are stored in memory and remain there even without the main or backup power source until altered by the user. Each sensor will have settings unique to its function and the Service Logger will select and display the correct menus for each sensor that is plugged in.

RECORDING DATA

One of the most important functions of the Service Logger is to record information over a period of time. This function is like a chart recorder except that the information is stored in memory rather than being printed on paper. The user can choose to print the informati o n, transfer the information to a computer fo r advanced analysis or long term storage, or review the information on the Service Logger’s display.

Page 4

Dual Temperature Adapter

In the case of the OM-60-MOD-TT Sensor, the temperature of each sensor will be recorded. Different sensors will, of course, record different information depending on the function of that sensor. The Service Logger has a memory capacity to record up to 4000 samples o f d a ta . It i s th e o p ti o n o f th e u ser to reco rd data to the maximum capacity of the Service Logg er o r to termi n ate a reco rd i n g when sufficient information has been gathered.

IMPORTANT ! Each new recording will erase any previously recorded information. It i s th e responsibility of the user to either print or store a previ ous recording prior to starting a new recording.

The first step in making a recording is to select the proper recording time and sample rate. If a sampling rate of 15 seconds is being used, then every 15 seconds the temperature of each temperature sensor will be measured and stored into digital memory. No record of information is made between each sample even though the display will continuously show the environment the OM-60MOD-TT Sensors are exposed to.

For a recording to accurately reflect a series of events, it is u p to the u ser to select a recording interval that best suits the particular application. In some situations maximum record i n g time may be sacrificed so tha t mo r e f r eq u e n t sa mpling may be accomplished. Long term monitoring will require less frequent sampling in favor of longer recording times.

The next step is to select how the Service Logger will record the information from the OM-60-MOD-TT sensor. There are 3 possible ways to record information.

PRINTING RECORDED DATA

After a recording has been made the user will probably want some way to view and analyze the recorded information. This is most easily accomplished by printing out the data samples. The printed data can be analyzed or stored fo r future reference. Several print options are available.

Filtering Printed Recordings

If the user were to print a recording which used all of the memory capacity of the Service Logger, this would b e a very lo n g reco rd o f 4000 d ata sa mp les. To print this out line by line on a standard computer printer would use over 60 sheets of paper! Obviously this would be a cumbersome and time consuming process. In most cases the information required from the record is only when the temperature changes. If the temperature remains constant, it is not necessary to print line after line of the same information.

Page 7

Dual Temperature Adapter

The Service Logger allows the user to select from 1° to 10° of temperature change from either temperature sensor to print on. What this means is that data samples that are less than the selected temperature change are ignored during the printing process and only when the temperature has changed by the selected amount is a sample printed out. That temperature becomes the new value to compare to and the temperature will ha ve to chan g e ag ain b y th e selected amount before another sample is printed.

One important point to remember is that even if a data sample is not printed the Service Logger still has to recall it from memory and compare it to the filter selection. Therefore, a printout may take up to 10 minutes for a scan of all 4000 data samples. This may sound complicated, but is easy to understand by using an example recording.

Example:

A recording has been made of 2 rooms in a building over a 30 hour period to determine whether or not heat is reaching both rooms. This means that a one data sample is recorded every 30 seconds. For the printout the user has selected a change of 2° from temperature sensor #1. Shown below would be a typical printout of the data using the above selections. (In a real printout there would be no spaces between the lines of printing, but in our example these were added to allow room for comments to be inserted.)

End of Data This indicates the end of the

recording and shows that the temperature remained within 2° of 72°F for the remainder of the recording period.

The above example shows that by using the filtering function the user can take a printout that would consume over 60 pages of paper and condense it into a single page.

*Note that only ONE sensor may be used as a temperature filter.

Printer Error Messages

If a printer is not connected and set to operate, an error messa ge will be displayed to alert the user to a printer problem.

There are several possible problems that may occur if the printer is not ready. The Service Logger will alert the user to a problem with the printer. As each printer has its own set of controls and settings, the user is recommended to consult the owners manual supplied with the printer.

This is an error message that appears when the printer is not connected or turned off. Make sure the printer cable is attached to both the

VIEWING RECORDED DATA

One of the features of the Service Logger is that recorded information may be read directly on the display. The same filter functions that are available for printing data are also available for reading data on the display. This allows the user to let the Service Logger scan the recorded data and display only the information that is of interest to the user. Without this function the user would have to manually scan a poten ti a l 4000 d a ta sa mp les to fi n d th e i n f o r mati on of interest.

TRANSFERRING DATA TO A COMPUTER

After a recording has been made, the user may download the data to any PC compatible computer. The advantage of doing this is that it allows the use of more sophisticated analysis tools as well as a long term storage. Unlike the Print and View functions no filtering options are available in this mode. The entire recording is sent to the computer. The supplied software will convert the data recording to an ASCII file which can then be imported into a variety of data analysis software, word pro cessin g , a n d d a ta b a se p r o g ra ms. It i s su g g ested th a t i f the user plans to download recorded da ta o n a reg ular b a si s to co p y the tran sfer program to the users hard disk.

To start the transfer program, insert the supplied d i skette i n dr ive A. Typ e “A:SUPCO” and follow the instructions on the computer screen. A README file is also included on the floppy diskette which has detailed instructions on the use of the transfer program and reflects the latest informatio n th at i s no t i ncluded in this manual.

IMPORTANT! To use this function the 25 pin cable (DB25 Male-M ale) must be c onnected to the Service Logger and the PC compatible computer printer port. If you are unsure of which connector is the printer port, c onsult the ow ners manual which was supplied with the computer.

The computer transfer cable can be purchased from OMEGA as part # OMCC6.
