When ambient temperatures are higher than the admissible working
temperature, the output current is > 20.5 mA.
PA also features an analogue voltage input which can be used as an al-
ternative to current output 2. The emissivity factor or a correction for re-
flected ambient temperature can be controlled using this voltage input.
Two serial interfaces (USB and RS485) are available. They enable the
user to change all operating parameters such as emissivity setting, tem-
perature range, smoothing function or output current range during run-
ning operations.
PA pyrometers allows for continuous temperature data output in a user-
configured cycle time.
4.1 Operating Controls and Display
The rear panel of the PA pyrometer has a 4-digit display and 3 push-
buttons. The display shows the current temperature or, during configura-
tion using the push-buttons, the display will show the corresponding pa-
rameter.
Whenever the display shows a parameter, the F1 Parameter LED (yel-
low) will light up. The function of the F2 Status LED (green) is user-
configurable. In its initial state when supplied to the customer the F2 LED
indicates current status for the switch able output Do1 as ready for oper-
ation.
