The external micrometer is equipped with a Proximity cable connection and the SIS. (Smart Inductive
Sensor) with maintenance of reference position, even when the instrument is in standby mode. Its
principle with non-rotary spindle allows a very fast positioning.
It includes the following functional features:
- Input of Preset values
- Selection of the measuring unit (mm/inch)
- Transfer of measuring value (Proximity connection).
- Protection against penetration of dust and splashing of liquids (oil, water), protection degree IP67
according to (IEC 60529 standard)
This protection degree is also guaranteed when using the Proximity connector.
The micrometer Megawhiz is extremely easy to operate because of its menu selection system.

MAINTENANCE
Keep the micrometer in a dry environment when not using it for a longer period of time to avoid
rust formation of the metallic parts. Do not close the measuring spindle with the anvil when not
in use. Keep a distance of 1-2 mm. Do not use aggressive products (alcohol, trichloroethylene or
others) to clean the plastic parts. Do not keep the micrometer in places which are exposed to sun,
heat or humidity. Important : dry carefully all metal parts of the instrument after effect of moisture to
guarantee a perfect mechanical functioning and to avoid rust formation.
After having pressed on a button, introduced the measuring unit, the instrument shows «SET» for
the initialization of the reference point. Bring back the measuring spindle on the anvil (or on a Gauge
block). Press then [SET] or [MODE]. The instrument is now ready (Check the Preset).
SWITCHING ON, INITIALIZATION

EN
Mode of reduced consumption without loss the reference position. The standby mode is activated
automatically after 20 minutes of no use. It can also be activated by pressing the [SET] key until
extinction of display.
The instrument awakes automatically in case of movement detection on thimble, by a pressure on a
button or when requesting Data.
STANDBY
In order to fully switch off the instrument (minimum power consumption), press the [SET] button until
the message «OFF» appears.
At this state no data is maintained and therefore the Reference position is lost.
The «SET» message will be displayed again during the next use (see “Switching ON”).
FULL SWITCH OFF

ALPA_MICROMETER_MEGAwhiz
The [MODE] key enables the selection of the different menus (each key stroke activates the
following menu). The [SET] key enables the activation of a function assigned to the corresponding
selected menu.
To avoid a wrong action, each menu is active only during 5s. This period passed, the instrument
switches automatically back to «Measuring Mode» as long as no action has been performed to the
[MODE] or [SET] key.
DESCRIPTION OF THE MENU SYSTEM
Preset makes it possible to introduce a reference value different from zero.
Press many times the [MODE] button until menu «PRE» appears. Then press the [SET] button to
activate the function Introduction of Preset. The display shows 00.000 or the last stored value of
Preset. The rst digit blinks.
Each push on the [SET] button modies the value of the digit above the cursor (±, 0..9).
PRESET MODE

EN
PRESET MODE
Each push on the [MODE] button moves the cursor to the right. A long press on the [MODE] button
validates the value of Preset and leaves the Preset menu.
The instrument automatically returns to «Measuring Mode» when there are no further actions
regarding the buttons [MODE] or [SET] for a period of 15s.
A push of 2s on the [SET] button assigns the Preset-value (or zero) to the current position of the
measuring spindles.
RESET, RECALL OF THE PRESET

ALPA_MICROMETER_MEGAwhiz
Repeatedly press the [MODE] button to display the [UNIT] menu. Presset then the [SET] button to
change the unit «MM» or «INCH».
CHANGING UNIT (MM/INCH)
Press [MODE] until the display shows « LOC». Then press [SET] to lock the instrument.
If the instrument is locked, the function send data (button [SET]) only is active.
A pressure of 5s on a button, unlocks the instrument.
LOCKING OF THE INSTRUMENT

EN
Press many times the [MODE] key until the menu «HOLD» is displayed. Then press the [SET] key to
switch «ON» or switch «OFF». Press [MODE] key to validate.
During measurement , press the [SET] key to freeze the value. A «H» appears in the display. A 2nd
pression on the [SET] key reactivate the dynamic value on display.
This function is useful when the display is not clearly in the eld of vision.
HOLD MODE
The external micrometer has a contact less data output. This data output enables the direct
connection to a computer or a printer using a Proximity connection cable.
A short press on the [SET] button transmits the current value to the data connection. The indicator
send Data is briey displayed.
For more information, see the instructions of the proximity cable.

REMOTE COMMANDS
The data request is done by the sending of the character ASCII <?>, followed by <CR> (carriage
return). The instrument also answers in the same way during the detection of an impulse pedals/
automat. The other commands are shown in the following table:
AOFF 0 / AOFF 1 Deactivates/activates the automatic switch-off
AOFF? Forwards the state of the automatic switch-off

LCAL? Sends the date of the last calibration(DD.MM.YYYY)
LCAL DD.MM.[YY]YY Sets the date of the last calibration
MM Activates the millimeter unit
NCAL? Sends the date of the next calibration (DD.MM.YYYY)

EN
NCAL DD.MM.[YY]YY Sets the date of the next calibration
NUM? Sends the instrument number
NUM XXXX Modies the instrument number (up to 10 characters)
OFF Switch instrument OFF
OUT 0 / OUT 1 Disables/enables the automatic data transmission
PRE? Sends the Preset value (±xxx.yyy[yy])
PRE ±XXX.YYYYYY Sets the Preset value (max. 200.0mm / 8.00’’)
? Sends the displayed value
