Q & A:
A room has an ambient room air temp of 70 Deg F, followed by a brief period at 50 Deg F for 5 seconds, then returning back to 70 Deg F again. Will the meter be able detect this temperature change and display it as a minimum reading ?.
I did an experiment on DTM-550 at the out flow gate of air conditioner from room
temperature of 78.8 deg F( 26 deg C).
The reading 59 deg F ( 15 deg C) takes 5 seconds.
The reading 50 deg F should take around 10 seconds.
There is no minimum reading button for DTM-550 but you can have " Hold" function
to read what you measure.
Please note this unit is not available for Fahrenheit display and only for Celsius.
