Time Interval Measurement - Int - Ecom Instruments Ex-Tacho 10 Manuel D'instructions

8.7.3 When a capture test is ready to commence, while
the Measure button is held On, press Programme
button once, at this point the instrument will switch
into high speed Time base mode, (0.1 Seconds)
and will capture the highest or lowest reading after
pressing the Programme button.
Releasing the On button will hold the reading and
cancel the Capture mode until another capture
measurement is required, when 8.7.3 should be
repeated.
8.8 Count measurement mode - cnt
8.8.1 Select mode as described in Measurement mode
selection section
8.8.2 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.
8.8.3 By contact method, fit contact adaptor, press
speed cone onto the end of the shaft, the
Instrument will count revs.
8.9 Linear Length Totalisation measurements - mt, ft, yd
8.9.1 Select any linear unit of measurement, press con-
tact wheel onto moving surface and commence
Count by pressing & holding Measure button On,
Count will increment until button is released.
8.9.2 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.

Time interval measurement - int

8.10.1 Select int mode through Measurement selection
mode
8.10.2 This mode allows measurement of time between
pulses from optical system (or contact adapter).
8.10.3 Optically the instrument will measure the time in
seconds between pulses, useful for cycle timing of
reciprocating machinery.
8.10.4 Time in seconds per revolution, which equals reci-
procal speed.
8.10.5 Very slow speeds can be measured in this mode
below 3 rpm.

8.11 Display orientation - Inverting function - All modes
8.11.1 The instrument can be used through 180 deg.
rotation (e.g. with the light beam pointing down
ward into a machine), the display inverts so that
normal reading can take place.
8.11.2 The UP Button selects normal mode for optical and
contact measurements.
8.11.3 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.
Operation Notes
Ensure the contact adapter rotates freely before use, do not
maintain contact for longer than 10 seconds at any one time.
Battery Replacement
Batteries must only be replaced with Duracell "Procell"
AAA cells.
The battery compartment lid must only be opened in a safe
area. To open the lid, first unscrew the security screw with a
special tool until it moves freely. The screw is a captive type
and should not be removed from the lid. Once the screw
moves freely, press the thumb grip on the lid and push/slide
the lid backwards and lift off.
The old batteries can then be replaced ensuring correct
orientation. Replaced the lid ensuring the security screw is
pulled upwards to avoid catching underneath. The base of
the lid is now pushed until a click is heard, tighten the secu-
rity screw and the unit is ready for use.
