Strain Indicator and Recorder
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 0.35mm dia.)
Bridge Configurations:
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.
Data Conversion:
High-resolution sigma-delta converter. 60Hz or 50Hz noise
rejection. User selectable.
Basic Range:
±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)
Gage Factor Settings:
Range 0.500 to 9.900.
Balance:
Single key operation to initiate automatic software balance.
Bridge Excitation:
1.5Vdc nominal. Readings are fully ratiometric, and not
degraded by variation in excitation voltage.
Communication Interface:
Universal Serial Bus with type B connector. Used for
transferring stored data and firmware.
Data Storage:
Media: Removable Multimedia Card (16Mb supplied) 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.
Analog Output:
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 15Vdc. AC adapter optional.
Operational Environment:
Temperature 0 to + 50°C. Humidity up to 90% RH, noncon-
densing.
