CHAPTER 2
Use in Quick SPC
TM
This operating mode has been designed in order to use the instrument directly on the
machine. Once the measurement has been performed correctly, its value is frozen
so that it may be transferred to the Quick SPC
TM
.
This operating mode is ideal when it is necessary to acquire the measurement at
a distance from the PC where the Quick SPC
TM
is installed (outside radio range).
In this way it is possible to acquire the measurement on the piece even when the
connection to the PC is interrupted. Once the measurement system is back within
radio range, and hence reconnected to the PC, it will be possible to send the acquired
measurement to the Quick SPC
TM
.
In order to use this operating mode correctly in Quick SPC
TM
, it is necessary to
program the measurement STEP as follows:
● STATIC - AUTOMATIC - Acquisition Sample: 1 - Elaboration Sample: 1
In this way:
● the measurement is acquired and frozen on the instrument by pressing
the central (Hold) button);
● the step is started (by means of the soft-key or an external input -
pedal) via the Quick SPC
TM
;
● the measurement is acquired by the instrument and store in the
Quick SPC
TM
;
● the step terminates automatically.
Use in Easy Acquisition
TM
This operating mode may be used only in the case of single acquisitions.
● Send From Button
The central button is used to send the measurement value. In this mode Quick Digit
TM
Bluetooth
®
Driver does not execute measurement value requests.
When the operator presses the central button, the Quick Digit
TM
Bluetooth
®
sends
the current value to the Quick Digit
TM
Bluetooth
®
Driver.
For each Quick Digit
TM
Bluetooth
®
programmed in Send From Button mode, an
input bit and summary (OR) bit of all the bits for the various congured devices are
displayed (see I/O Bit map in paragraph 5.3).
When a Quick Digit
TM
Bluetooth
®
(in Send From Button mode) sends a measurement
value, the bit associated with that device and the OR bit are activated.
These bits remain active (1) for 400 ms, after which they are deactivated (0).
From the moment the bits assume the active state (0>1 transition), the Driver
maintains the measurement value valid for 500 ms.
When the bits change state from 0 to 1, it noties the application that it has 500 ms
to read the value from the driver.
