How To Measure - Metro DataVac DPC 20 User Manual

3. HOW TO MEASURE

When switched on, the manometer is automatically in measurement mode.
First of all, make sure that the manometer is provided with an adapter appropriate for
the cans on which you wish to measure the pressure. To make the measurement,
place the adapter firmly on the valve of the can. If the display parameter was set to
«instantaneous value » (see 2.2 Display), the measured value must be read while
maintaining the whole in position. If you choose to display « maximum value » or
« minimum value », you can remove the manometer to read the value that remains
recorded for display.
When not used for more than 1 minute (displaying zero), the manometer is
automatically set on stand-by. It will be activated again, (always to be done at
atmospheric pressure) by pressing

by the serial link).
The defined sample size will determine whether the measurement will be memorized
or not (see 2.4 Sample size). Recording measurements is necessary if they are to be
analyzed statistically.
3.1 Measuring without recording of values
If sample size is set to zero, no measurements are recorded in the DPC 20. This
implies using the DPC 20 as an ordinary manometer without recording
measurements. When setting sample size to zero, pressing
resets the memory and displays a zero.
3.2 Measuring with recording of values (SPC application)
If sample size is set to a value above zero, measurements can be recorded by
M
pressing after each measurement. The DPC 20 will accept recording the number
of measurements defined as sample size. To enable monitoring the number of values
recorded, every time
is displayed.
If you wish to erase the recorded measurements press
time. The manometer will then display 00.
The recorded values can subsequently be transferred by serial link (see 4.2 Walking
around measurements with data download).
