Function
Indicator lights when source A temperature is stable
and within 0.02°C of the set absolute or differential
temperature.
Pushbutton switch enables differential temperature
control.
Source A temperature is slaved to the ambient
sensor temperature.
Source A temperature can be
positive or negative in relationship to the ambient
sensor temperature.
If positive, source A temperature is regulated above
the ambient temperature by the differential temperature
set by the thumbwheel switches.
If negative, source A temperature is regulated below
the ambient temperature by the differential temperature
set by the thumbwheel switches.
Indicator lights to show differential temperature
control is selected.
Pushbutton switch enables absolute temperature control
of blackbody connected to source A.
Thumbwheel switch
setting will directly determine temperature of
blackbody surface.
Indicator lights to show absolute temperature control
is selected.
Pushbutton switch selects display to show temperature
difference between source C and source A.
Indicator lights to show temperature difference between
source C and source A is displayed.
Pushbutton switch selects display to show temperature
difference between source B and source A.
Indicator lights to show temperature difference between
source B and source A is displayed.
Pushbutton switch selects display to show temperature
difference between source A and the ambient sensor.
Indicator lights to show temperature difference between
source A and ambient sensor is displayed.
