OM‐90 Series Data Loggers Quick Reference Guide (Models OM‐91 & OM‐92) Description The OM‐90 Series are portable, battery operated, temperature and humidity data loggers able to store 65,520 samples of both temperature and humidity along with a time stamp. The data logger runs off of a CR2450 coin cell battery that enables it to run for over 4 years. This Quick Reference Guide gets you started with the logger with the most basic functions to have you up and running with your logger in a matter of minutes. The OM‐90 Series today comes in two versions; OM‐91 is a temperature only version and OM‐92 is a temperature and humidity logger. This quick reference guide applies for both versions. Battery Installation The data logger runs from a standard coin cell battery. We recommend a CR2450 620mAH Coin cell battery. There are different manufacturers but a good one is Panasonic CR‐2450/G1AN. You can find it easily on the web from different places such as www.digikey.com and www2.mouser.com. The key thing is to choose a CR2450 battery with high capacity since this will translate into a longer logger battery life. First remove the data logger cover by unscrewing the two fastener screws (#1 Philips) at the rear of the logger. Revision 1.0.4 Page 2... -
