7.2.4 Valley temperature measurement
Valley
temperature measurement is the inverse of Peak temperature
measurement, in that it allows you to monitor the lowest temperature value
rather than the highest. Temperature measurement starts when the trigger is
pressed in and continues until the trigger is released (See Fig. 7-4).
The temperature is updated instantaneously and the value is viewed in the
instrument eyepiece.

a
Thermometer trigger pressed
b
Valley temperature value on display jumps to instantaneous temperature
value and is held on display with rise in object temperature
c
Object temperature falls, new Valley temperature value reached, display
updated as object temperature falls. Object temperature rises, last Valley
temperature value held on display
d
Object temperature falls, new Valley temperature value reached, display
updated as object temperature falls. Object temperature rises, last Valley
temperature value held on display
e
Trigger released, last Valley temperature value frozen on display
f
Trigger pressed
g
Valley temperature value on display jumps to instantaneous temperature
value (even if higher than last Valley value held before trigger release).
Display updated as object temperature falls
h
Object temperature rises, last Valley temperature value held on display
