10. Measuring using Measuring-Menus
10.6.2 Wet Bulb Globe Temperature
The stress caused in heat-exposed work-
places can be evaluated in terms of their wet
bulb globe temperature calculated according
to the following formula:
WBGT=0.1TT + 0.7HTN + 0.2GT (s.man.
3.1.4)
To measure the dry temperature (DT) and
the natural humid temperature (HT) a psy-
chrometer (FN A848-WB) with turn-off motor
is connected to socket M0 and a Pt100 globe
thermometer is connected to socket M1. The
output on channel 11 is programmed to
WBGT; (for this device the factor 0.2 must
not be programmed !).
10.7 User Menus
When studying the measurement menus you may have noticed that the display
of the meas. value and the combination of functions does not always match
your applications in an optimum way. Therefore, you can freely configure the
three user menus
U1
to
U3
, in addition to the standard measuring menus using
the software AMR-Control. You can use the following list of functions to individ-
ually place the functions you require, in any sequence, on your display up to
the available space of 13 lines. In addition to the meas. functions that have
been described before, it is possible to use times and cycles for the process
control (s. 11.1.) and most of the sensor programming functions (s. 11.3).
