Description
The Model 610 strain gage amplifier exhibits the performance characteristics and controls derived from 20 years of customer-oriented experience. It features very low output noise, broadband response and many other conveniences, all combined in one moderately priced module.
Specifications
Bridge configuration: Quarter dynamic and full bridges are switch selectable on the front panel. Static and
half bridges are selectable by changing the internal completion header. This unit also can be used as a general purpose differential amplifier
Bridge completion: Internal header mounts customer-specified precision completion resistors
Bridge excitation: Front panel adjustable 1.25VDC to 15.0VDC constant voltage excitation or fixed 15mA or 30mA constant current excitation; front panel on/off switch
Bridge balance: Front panel trimpot allows bridge to
be manually balanced
Operating modes: Switch selects Zero, AC coupled, External cal signal, DC coupled, or DC cal
Gain: Front panel switch selectable gains of 1, 2, 5,
10, 20, 50, 100, 200, 500, 1000, 2000, 5000 with gain vernier
Frequency response: DC to 50kHz, with board-mounted dip switch selectable two-pole active filter at 10Hz, 500Hz, 1kHz, 5kHz, 16kHz, and 32kHz -3dB frequencies
AC coupled response: Board-mounted toggle switch selects 10Hz highpass or 0.4Hz highpass filter
