Compact Instruments Advent A2103 Mode D'emploi page 6

8. Count measurement mode - cnt
8.1. Select mode as described in Measurement mode selection section
8.2. For rev Counting optically, point the light beam at the target and the instrument will
measure all revs. (pulses) until button is released, the display will hold Count for 1
minute.
8.3. By contact method, fit contact adaptor, press speed cone onto the end of the shaft, the
Instrument will count revs.
9. Linear Length Totalisation measurements - mt, ft, yd
9.1. Select any linear unit of measurement, press contact wheel onto moving surface and
commence Count by pressing & holding Measure button On, Count will increment until
button is released.
9.2. The displayed value can be scanned through the equivalent values of Metres, Feet,
Yards, Count by pressing the Programming button, the instrument automatically calculates
the appropriate reading.
Note. Measurement Units will be stored in originally programmed parameter e.g. metres.
10. Time interval measurement - int
10.1. Select int mode through Measurement selection mode
10.2. This mode allows measurement of Time between pulses from optical system (or contactor).
10.3. Optically the instrument will measure the time in seconds between pulses, useful for cycle timing
of reciprocating machinery.
10.4. (Time in seconds per revolution), which equals reciprocal speed.
10.5. Very slow speeds can be measured in this mode below 3 rpm.
11. Display orientation - Inverting function - All modes
11.1. The instrument can be used through 180 deg. rotation (e.g. with the light beam pointing
downward into a machine), the display inverts so that normal reading can take place.
11.2. The UP Button selects normal mode for optical and contact measurements.
11.3. The Down button selects the display inversion mode and the whole display including relevant
icons will reverse through 180 degrees allowing access to difficult applications.
