HARDWARE SPECIFICATIONS
All specifications nominal or typical at +23°C unless
noted.
Inputs
Eccentric-lever-release terminal blocks accept up to four
independent bridge inputs. Accommodates 16-28 AWG
(1.3 to 0.35 mm diameter) wire.
The Transducer Option includes four 10-pin bayonet
locking circular connectors mounted on the side of the
case and wired in parallel to the lever-release terminal
blocks. The supplied mating connector has a 0.046 inch
(1.17 mm) diameter solder well.
BridgeConfigurations
Quarter-, half-, and full-bridge circuits. Internal bridge
completion provided for 120Ω, 350Ω and 1000Ω quarter
bridges, 60 to 2000Ω half or full bridge.
Display
Full dot-matrix structure with 128 dots x 64 dots FSTN
positive, gray transflective LCD with backlight. Display
update is twice a second.
DataConversion
High-resolution sigma-delta converter. 60 Hz or 50 Hz
noise rejection. User selectable.
BasicRange
±31,000 microstrain (±1 microstrain resolution) at Gage
Factor = 2.000
Accuracy
±0.1% of reading ±3 counts. (Normal mode operation at
Gage Factor = 2.000)
GageFactorSettings
Range 0.500 to 9.900
Balance
Single key operation to initiate automatic software
balance
BridgeExcitation
1.5 VDC nominal. Readings are fully ratiometric, and not
degraded by variation in excitation voltage
CommunicationInterface
Universal Serial Bus with type B connector. Used for
transferring stored data and firmware.
DataStorage
Media: Removable Secure Digital or Multimedia Card
(2GB max).
Data Recording Rate: 1 reading per second
maximum.
Calibration
Shunt calibration across each dummy resistor to simulate
5000 microstrain (±0.1%). Remote calibration supported
via accessible switch contacts at input terminal block.
AnalogOutput
BNC connector. 0 to 2.5V maximum output. Device
impedance of 2000Ω or greater. 480 samples/second
DAC output update rate.
Power
Internal battery pack using two “D” cells. Battery life up
to 600 hours (single channel, normal mode.) Can also
be powered from USB or by external battery or other
power source of 6 to 15 VDC. AC adapter optional
(Model P3-A105).
OperationalEnvironment
Temperature 0 to + 50°C. Humidity up to 90% RH,
noncondensing
