A number of operational characteristics can be configured prior to mounting or wiring the amplifier. We
recommended that you first familiarize yourself with the internal switch locations, settings, and potentiometers by
opening the snap-on access cover. Figure 4 illustrates the location of configurable items on each of the printed
circuit boards.
Use an approved anti-static wrist strap when adjusting any switch setting o r potentiometers on the
amplifier.
Switch PCB Location Function
J3 Input
Configures Excitation voltage for 5.0 or 10.0 VDC. The amplifier is factory set at (setting 1-2 ) for
5.0V
J8 Input
Selects left channel only (setting 2-3) or LCH + RCH (setting 1-2) as input to summing amplifier
stage. Slide the jumper switch to (1-2) for normal operation with two transducers. Refer to
setup/calibration section for more information.
J1 Input
Connects completion resistances of RCH transducer input to ½ of excitation voltage
(setting 1-2). Slide the jumper switch to setting (2-3) for normal operation with Ultra Full-Bridge
transducers. Slide jumper switch to setting (1-2) if the channel is unused.
J2 Input
Connects Completion resistances of LCH transducer input to ½ of excitation voltage
(setting 1-2). Slide the jumper switch to setting (2-3) for normal operation with Ultra Full-Bridge. Slide
the jumper switch to setting (1-2) if the channel is unused.
J10
J9
J7
Input
Sets voltage gain of LCH Instrumentation amplifier to 5, 25, 125 or 620. The jumper switches are
factory set to (1-2) for minimum gain (Av = 5). Refer to section 2.9 for more information on setting
Gain select switches.
J6
J5
J4
Input
Sets the fixed gain of RCH Instrumentation amplifier. The jumper switches are factory set to
(1-2) for minimum gain (Av=8).
J1 Output
Configures meter output stage for +/- 2V F.S. or +/- 1 mA F.S. The jumper switch is factory set to (1-
2) for voltage output. Voltage and current modes use different terminals.
J2 Output
Selects meter damping 0.3 Hz or 3.7 Hz. The jumper switch is set to (2-3) for minimum damping. (3.7
Hz)
