The last popup balloon or dialog states "Your new hardware is installed and ready to use," and the LED on the 
U

MDAS 0802DA

 should flash and then remain lit. This indicates that communication is established between the 

U

MDAS 0802DA

 and your computer. 

 

On most computers, you can install up to two 

UMDAS 0802DA

 units. If you need to connect more than two 

UMDAS 

0802DA

units to your computer, contact Tech Support by phone (

203-483-9966

), fax (

203-483-9024

), or email

Caution!

 

Do not disconnect 

any

 device from the USB bus while the computer is communicating with the 

U

MDAS 0802DA

, or you may lose data and/or your ability to communicate with 

your unit.

 

If the LED turns off 

If the LED is illuminated but then turns off, the computer has lost communication with the 

UMDAS 0802DA

. To 

restore communication, disconnect the USB cable from the computer, and then reconnect it. This should restore 
communication, and the LED should turn back 

on

Allow the 

UMDAS 0802DA

 to operate for at least 30 minutes before using the device. This warm up time is 

required to achieve the specified rated accuracy of measurements. 

Calibrating the 

UMDAS 0802DA

 

The U

MDAS 0802DA

 is shipped fully calibrated. Calibration coefficients are stored in EEPROM. Return the device 

to 

CyberResearch, Inc.

 when calibration is required. The normal calibration interval is once 

per year.
