Page 2: Operating Instructions
Brownlee Precision Model 410 Four-Channel Instrumentation Amplifier Power: The Model 410‟s power requirements are 120 VAC, 47-63 Hz unless otherwise indicated on the back panel near the power connector. Run an IEC line cord from a wall socket to the back panel power connector. - Page 3 Amplifier Settings: There are 5 main parameters, which can be adjusted on each amplifier channel: Gain, Lowpass Filter cutoff frequency, Output Offset voltage, Input Selection, and Input Coupling. There is a button corresponding to each one of these parameters. Pushing one of these buttons puts that parameter‟s value on the 8-digit alphanumeric display.
- Page 4 To select which input is to be amplified, push the „Input Select‟ button and turn the knob until desired configuration is displayed. “Gnd” ignores both input lines and internally ties the inputs to 0 Volts for equipment setup and testing. The “A” setting amplifies the single-ended signal on the A input.
- Page 5 The electronic components at each stage of the amplifier have inherent offset voltages, which could appear as a shift of the “zero” level of the output. The Brownlee Precision Model 410 has a self- trimming feature, which compensates for these errors automatically.
- Page 6 Lithium Rechargeable Battery: Very unlikely this battery will lose its charge. If the amplifier is no longer holding its settings when power is turned off, or you find you must frequently push the reset button to turn the amplifier on, then contact Brownlee Precision Company for replacement instructions.
