Note
Setting the Averager response speed to a value faster than that quoted
in the specification for your thermometer will not produce an increase
in response speed beyond the specified value. e.g. Fastest possible re-
sponse speed for a V1 UNO is 15ms.

4.4.2 Peak Picker
The Peak picker time function is selected by setting switch, SW5, to position
2 (i.e. down). The Peak picker decay rate can be set, via switch SW4, to any
one of the ten values shown in Fig. 10.
The CMD (Command) input, available between pins 3 and 7 of the thermom-
eter electrical connector, enables remote resetting of the Peak picker time
function. (Refer to Section 3.8.1). When the CMD input is open circuit, the
Peak picker operates under the control of switches SW4 and SW5. When the
CMD input is short circuit, the Peak picker function is RESET and the output
signal reverts to tracking the input, regardless of the setting switches SW4
and SW5.
A graphical explanation of the Peak time function is given in Fig. 12.
