Operation of model A2013/LSR
Ex works setting - rpm mode, non autoranging
1. Programming - measurement mode selection
All measurement modes are chosen by this method and once confirmed, selected mode remains in
permanent memory until re-programmed by the user.
1.1.
To change mode hold programme button on and press up measure button and then release
both buttons, the display will now illuminate all icons, and the current range will flash.
1.2.
To select new measurement mode press either up or down button to scan through the
modes, when the required mode icons flash release measure button & press programme
button once to confirm settings.
For non-speed modes the unit is now programmed and ready for use.
1.3.
To select
mx, mn, av.
modes continue to scan through each one, if the mode is not required,
stop scan when all three icons illuminate continuously, then press programme button once.
The instrument is now ready to use.
Set parameters will be retained until reprogrammed
2. Optical revolutions speed measurement - rpm or rps.
2.1.
Ensure batteries are correctly fitted.
2.2.
Attach small reflective target to machine shaft (typically 6mm x 25mm, less for laser version)
2.3.
Start machine and point the tachometer towards the target.
2.4.
Press and hold either of the on/off buttons to suit application and hold continuously.
2.5.
Aim light beam onto target, ensure “on-target” sign is glowing or flashing steadily
2.6.
Read off rpm, releasing button will hold last reading.
2.7.
Last rpm reading will be held in display for 1 minute.
2.8.
Press the On button to zero reading or take another measurement.
3. Contact revolution speed measurement - rpm or rps.
3.1.
Fit contact adapter into the tachometer and ensure a good click fit connection.
3.2.
Start machine and make clean contact with the recess in shaft end (wheel can be removed).
3.3.
Contact the shaft end via the rubber cone, ensure a steady firm pressure is applied and that
the instrument is accurately in line with the machine shaft.
3.4.
Press and hold either up or down measure button as required & read speed
3.5.
Releasing the
On
switch will hold the reading automatically for 1 minute, automatic switch off.
4. Linear contact speeds measurement - metres, yds, feet etc.
4.1.
Fit contact adapter as above.
4.2.
Keeping the
on
button pressed, now place the contact wheel on the moving surface and read
the linear rate, ensure wheel is perpendicular to the moving surface.
4.3.
Releasing the on button will then hold the last reading in the display for 1 min.
4.4.
The instrument retains selected measurement mode for further linear measurements after
switch off until programmed to a different mode.
5. Autorange selection - speed modes only
5.1.
While taking a measurement using either up or down measure button, the user can toggle
between auto and non-auto mode by pressing the programme button, in the auto mode, the
A
icon will illuminate.
6. Average speed monitoring mode - av icon.
6.1.
Average speed mode
- this mode provides a rolling average of the last 8 measured values.
7. Operation of Maximum & Minimum modes Speed Capture functions - mx, mn.
7.1.
Having selected the required mode, i.e. Maximum or Minimum, (mx).
7.2.
You are now ready to Ca
pture a reading “On Demand” but continuing to operate normally.
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 Timebase
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 7.3. should be repeated.
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.
12. Pulse output facility
12.1
The A2103/LSR/001 can be connected to external measurement equipment with a TTL
compatible input.
12.2
Connect the lead supplied to the tachometer output socket. The Tachometer will turn on
automatically and remain powered as long as the lead is attached.
12.3
The tachometer will give a 5V TTL compatible signal when the laser is on target.
