1. FEATURES
The EG-225 compact digital linear gauge conforms to AGD Group
II mechanical specifications. Its excellent response enables
spindle travel up to 20 in/s (500 mm/s). With a resolution of
0.00005, it is possible to make measurements with a stroke of 1
inch. Three measurement functions (normal, absolute zero, and
preset) are available for selection, depending upon the particu-
lar application.
In addition, it features selection of either English or metric read-
out and has a serial data output.
• Three measurement functions: normal, absolute zero, preset
• A stem, back and body that satisfy AGD Group II specifica-
tions make the EG-225 directly interchangeable with existing
mechanical gauges.
Combined with commercially available fixture, the EG-225 can
be used as a depth gauge or snap gauge.
• A linear gauge technique is used to provide a high degree of
ruggedness and highly stable accuracy.
• Selectable English or metric unit.
• Any arbitrary position can be set as the reference point (in the
normal function, this is set at zero, and in the preset function,
this is set at a given value).
• By using a direction switch, it is possible to select the counting
direction. (In the absolute zero function, the direction is fixed
as the direction, and for the preset function, the direction is
fixed as the direction selected for the normal function.)
• Switched mode display of maximum value, minimum value and
range. (In the absolute (ABS) zero function, the MAX., MIN., R
mode function does not operate.)
• Dual power supply enables operation from either an AC line
(using an AC adaptor) or a selfcontained rechargeable bat-
tery.
• Can be combined with RQ-2110 Printer to perform data re-
cording and statistical calculations.
• Can be connected to RS-232C devices via the BH-100 Inter-
face Unit, enabling highly efficient SPC processing.
