1. INTRODUCTION Many thanks for selecting the HTG79 from IROX. In your hands, you hold a high-quality thermo/hygrometer which we have equipped with additional functions that have above-average design and functionality in a market comparison. These include the measurement memory where in addition to the maximum and lowest values also the time and the date of the measurement per channel are recorded (the so-called ‘time stamp’).

2.2 KEYS View from front CHANNEL / + (press briefly) - In normal operating mode: Changes from channel to channel ( --> 1 --> 2 --> 3 --> 4 --> 5 --> --> etc) - In the various setting modes: Increases the value to be set (hold pressed for fast run through) MEMORY / - (press briefly) - In normal operating mode: Call-up of the data from the thermo/hygro memory (MAX -->...
Now close the battery compartment. Directly after the activation of the batteries, all segments are displayed for a few seconds on the display. The HTG79 then begins with the time at 0:00 and 1.1.08 and the search of available sensors on all 5 channels.
Each sensor is read by the device once a minute. If more than 8 readings are read one after the other without data, lines appear in the display for this channel and the HTG79 then stops any other reception attempts after this for 8 hours.

5.2 THERMO/HYGROMETER WITH ALARM With regard to operation, the HTG79 is in a 'sleep mode’ when no key is pressed for more than 2 minutes. This status is then recognised by the fact that on the left-hand side of the display neither the symbol nor the number in the channel display is flashing.

5.2.4 Temperature and humidity alarm The alarm function is programmed individually per channel ( / CH1..CH5). Each alarm is defined by an upper and lower limit of the temperature and/or the rel. humidity. If one of them is exceeded or undercut, an acoustic and optical alarm is triggered.
Should you notice deviations which make it difficult for you to operate and use the instrument you may at any time download the latest manual onto your PC free of charge at www.irox.com (please refer to the version number of the manual).
