MINNOW LOGGER
Quick Reference Guide(Minnow 1.0T & Minnow 1.0TH)

Description
The Minnow Logger is a portable, battery operated,temperature and humidity data logger able to store 65,520
samples of both temperature and humidity along with a timestamp. The Minnow Logger runs off of a CR2450 coin cellbattery 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 withyour logger in a matter of minutes.
The Minnow product today comes in two versions; Minnow
1.0T is a temperature only version and Minnow 1.0TH is atemperature and humidity logger. This quick reference guideapplies for both versions.

Battery Installation
The Minnow logger runs from a standard coin cell battery. We recommend a CR2450 620mAH Coin cellbattery. 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, www2.mouser.com and probably in yourlocal supermarket. 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 Minnow cover by unscrewing the two fastener screws (#1 Philips) at the rear of the logger.

Then remove the circuit board from the box (use soft tool or fingernail to remove)

Finally re-attach the cover and tighten the fastener screws again (be careful not to over tighten).
