Quick Start
This section briefly explains the basics of setting up and operating your thermo-hygrometer.
Unpacking
Carefully unpack the thermo-hygrometer and inspect the instrument to make sure all compo-
nents are present and in satisfactory condition. Verify that the following items are present:
1620A Thermo-Hygrometer
●
AC adapter and power cord

Manual
●
Report of calibration
●
Wall mount bracket
●
Sensor
●
9V battery
●
If all items are not present, contact an Authorized Service Center.
Use Proper Care
First and most important is to understand the safety issues related to the thermo-hygrometer.
Carefully read the Safety Information section at the beginning of this guide.
The thermo-hygrometer and sensors used with it are sensitive instruments that can be easily
damaged. Always handle these devices with care. DO NOT allow them to be dropped, struck,
stressed, or over-heated.
Learn About the Features and Components
Familiarize yourself with the features and accessories of the thermo-hygrometer by reading the
Parts and Controls section of this guide.
Install the Battery
To maintain uninterrupted measurement when power outages occur, you must install the in-
cluded battery into the rear battery compartment. A standard 9V alkaline battery (NEDA 1604A
or IEC 6LR61) is recommended. With a fresh alkaline battery installed, the thermo-hygrometer
will continue to measure and record temperature and relative humidity during a power outage
for up to 16 hours, typically. However, without external power, the display will be inoperable.
