measurement type will automatically log if it is needed to calculate the
measurement type on the large digits when the SAMPLE key is pressed.
For example, if dew point is being displayed on the large display digits
and SAMPLE is pressed, then dew point, humidity, and temperature will
all be stored automatically because dew point is calculated using
humidity and temperature. Table 3.1 shows what measurements are
stored automatically when a specific measurement type is on the
display.

Press and hold the SAMPLE key to view, enter, or change data storage
options. "SET" lights up on the small display. The velocity units light
up, and the large display says "On" or "AUtO", depending on how it
was set previously. Use
ENTER to accept setting and advance to next parameter. The flow rate
units light up, and lower display says "On" or "AUtO", depending on
how it was set previously. Use
press ENTER to accept setting and advance to next measurement. This
pattern will continue through the following measurements: differential
pressure, temperature, relative humidity, dew point temperature, wet
bulb temperature, and heat flow. Follow the same instructions as set
forth above for each parameter. Once all the measurement parameters
have been displayed, the instrument will return to measurement mode.
