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 included 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.

Getting Started Guide

Connect the Sensor

The sensor for channel 1 connects to the socket at the top-right, and the sensor for channel 2, if used, connects to the socket on the right side. Either sensor may be used with an optional extension cable up to 100 feet (30 meters) in length.

Connect the Power Source

The thermo-hygrometer draws power from the provided power adapter. Plug the adapter into a wall outlet of the appropriate voltage and insert the DC plug into the DC power input of the thermo-hygrometer.

Switch the Power On

Power is turned on and off with the power switch located below the stand on the back panel. To switch the power on, toggle the power switch to the ‘ ’ position. To switch power off, toggle the power switch to the ‘ ’ position. The instrument takes a few seconds to power up, initialize, and begin normal operation. A self-test is performed, displaying the channel configuration and status of the system, calibration, % battery power, memory, and buttons. If the thermo-hygrometer calibration has expired and the alert message is enabled, the user is notified and must press the Enter button to continue initialization. If an error message is displayed on power up see the

Troubleshooting section in the User’s Guide.

Measure Temperature

After initialization, the temperature and relative humidity measurements for the enabled channels are displayed. If recording is enabled, the measurements will be automatically stored in memory. The display can be configured to display the measurements in a variety of numerical and graphical formats. For information on the various modes of operation of the thermo-hygrometer, see the Menu Functions section of the User’s Guide.
