PRECAUTIONS AND MAINTENANCE
e Dust, dirt and other foreign obstacles should be
wiped clean from the base, scriber, column of the
height gage and the surface plate, before measure-
ment.
e Do not expose the height gage to cutting fluids,
water, dust, dirt and hot draft etc.
e Be sure to turn off the power after using.
e Cover the height gage by the dust cover after using
with its slider lowered but not to touch the surface
plate by the scriber.
e When the height gage is not on service for a long
time take the following measure.
- Take out the batteries.
- Remove the scriber and apply a grease to the
base and ihe scriber holding face.
- Apply an anti-corrosiveoil to the columns.
- Dust, dirt etc.on the rack on the column should
be totally removed by tooth brush and the like.

Mitutoyo Digimatic height gage (HDM)is an LCD dis-
play type of digital height gage having various fea-
tures: it has two measuring systems,
ABS (absolute)
and INC (incremental) ineither of which you can use
zero set function, hold function and preset function
according to the measuring requirements and for lay-
out job as well. Furthermore, it has data output
capability for statistical data processing by
Mitutoyo's Digimatic Mini-Processor such as DP-1,
DP-2and so on.
Also possible to use with a height gage is
a Mitutoyo's
touch signal probe specially developed to increase
efficiency of measurement by height gage.
Please go through this operation manual to make the
best use of your height gage.

2. 4 ABS and INC measuring systems
The Digimatic height gage
HDM has two measuring
systems,
ABS (absolute) and INC (incremental), for
selective use according to measuring requirements.
A
mode sign, ABS or I NC, comes upon the display to
show in which mode the gage
is servicing. Outline of
each mode
is shown below.
I) ABS mode
When the height gage is turned on, ABS sign comes
upon the display together with zero indication
(0.OOmm or 0.0000 in.), showing that the current
slider position (or scriber position) is determined
as
origin (absolutezero)
