Instrumentation amplifier for student experiments 8532161

1. Description
The instrumentation amplifier for students' ex-
periments is used in conjunction with a simple
voltmeter to measure very small voltages and cur-
rents.
The device consists of an operational amplifier and
a special preamplifier, owing to which a high gain
6
factor (10
), a low offset voltage and an excellent
long-term stability can be achieved. The amplifier
is used for both AC/DC voltage and AC/DC current. A
conventional voltmeter (measuring range: 1 V DC
or 3 V AC) serves as an indicating instrument. Addi-
tional calibration of the device is not required.
