Manual for use of thermometer-hygrometer ATAL ATC11 with surface temperature probe Instrument is designed for measurement of temperature and relative humidity (attached sensors) and temperature from the built in magnetic surface probe. It enables to display the dew point temperature and the difference between surface temperature and dew point temperature. Measured values are displayed on a dual line LCD display.

Battery life depends on selected display refresh mode (see below). In FAST mode display is refreshed in shortest possible interval with highest current consumption. In dynamic mode display is refreshed in interval up to 5 s in case measured values remain stable. Refresh interval is shortened to approximately 0.7 s only if measured values change.

Press HOLD key in the default mode (displaying of actual measured value) to store actual measured values to internal memory (indicated by short beep). Anytime it is possible to display stored values from MENU (see below). Each pressing of the HOLD key in the default mode causes values stored in HOLD memory are replaced with actual ones.

if measured values are stable. If measured values change, refresh interval decreases to approximately 0.7 s. This dynamic mode prolongs battery life significantly. Select the desired mode by ENTER key. Notice: if battery voltage is low, the FAST mode is out of operation to reduce current consumption independently on this selection.

OFF. If it happens (or if battery is totally discharged), it is necessary to set again in appropriate menu selection LCD refreshment mode (d.REF.), alarm audio indication (AUDI) and clear the minimum and maximum memory (CLR). ATAL instruments passed the following electromagnetic compatibility (EMC) tests: radiation: EN 55022 class B...
