significant count)
Tare Capacity: 10% of full scale in pound or ounce mode
Full Scale Deflection: 0.010"
Analog Output: 0 to ±2.0 VDC full scale, accurate to ±0.018 Volt

Weight: Instrument: 1-1/4 lbs (4 lb shipping weight)
The DFGS offers the highest level of sophistication, accuracy
and operation features within a single digital force gauge
product. Its rapid internal sampling rate, set point
capability and other programmable test parameters are well
suited for demanding R&D requirements as well as precise
production floor applications.
The standard bi-directional RS232 interface permits on demand
data transmission as well as peripheral control of all gauge
keypad functions. The highly accurate analog output
voltage provides for precise graphing of the force curve. When
integrated with a Chatillon TCD-200, LRX and LRX
PLUS digitally controlled test stand, the DFGS becomes
the heart of an extremely versatile tester system.
Operation Features
- Internal digital sampling rate of 5000 samples per second
- Programmable high and low force set points with audible
indicator and RS232 output signal for stopping motor drive
on Chatillon TCD-200, LRX and LRX
PLUS digital test stands or cycling the stand between
the set points. Operator may configure audible indicator
and/or RS232 output signal inactive while maintaining set
point values in memory.
- Peak function automatically captures and stores highest
instantaneous reading within each test. The peak
function may be engaged prior to testing to freeze the
display at the highest reading. It may also be engaged
after the test to display the peak value stored. The "zero" and
Star keys clear peak memory.
- Tension/compression modes are indicated by "T" for
tension or "C" for compression upon force application.
In the digital output, tension values are identified with
a minus sign
- Contact closure, force capture function can capture the
instantaneous electric contact force within keypads, buttons,
switches, etc. In this application, the test contacts
are electrically connected to the DFGS via two pins on
the output connector. Upon contact closure, the DFGS
is electrically prompted to freeze the digital display
as well as the analog output level.
- Selectable units of measurement: lb, kg or N (250 gram
gauge reads in units of oz, g or N)
- Push button calibration in any selected units
- Rechargeable battery or AC operation allows 8 hour continuous
battery operation with 12-14 hour charge. Low battery indicator
on display. Continuous AC operation via charger/AC adaptor
- Auto shut-off function preserves battery life. DFGS shuts
off if idle for 10 minutes. Operator may deactivate this
feature if undesirable.
- Available for 110 VAC or 220 VAC
Output/Interface Features

test stand |
- Bi-directional RS232 interface for data transmission
as well as peripheral control of all gauge keypad functions. Digital
data transmission up to 100 data points per second may
be accomplished via the interface. Data transmission parameters
are user-selectable. (Baud rates from 300 to 19,200). When
interfaced with a Chatillon TCD-200, LRX or LRX
PLUS digital test stand, the DFGS may be programmed
to transmit an RS232 signal upon reaching a force set point
in order to stop the test stand motor or cycle the stand
between force set points.
- Mitutoyo output (modified BCD) for use with Mitutoyo
brand processors
- Precise Analog Output: 0 to ±2.0 VDC full scale
with accuracy of ±0.18 volts. "Zero" key
will zero analog output as well as display for preloads
applications
Physical Design Features
- Die cast metal reversible housing. Split housing design
permits upright display whether gauge is hand held or test
stand mounted.
- Easy to read 1/2" high LCD display with 4-1/2 digits
for forced value. Smaller characters within the display
indicate units of measurement, test mode, set point and
low battery
- 9 key membrane keypad
- 2 separate rear mounting hole patterns (#10-32 thread)
- #10-32 x 3/16 long thread on load cell shaft
- Output connector: 12 pin "Hirose" design
Standard Accessories:
Stainless steel attachments include a flat head, hook, cone,
chisel and extension rod. Gauge, battery charger, attachments,
Allen wrench and operation manual are furnished in a cushioned
carrying case.
