FunctionThe amplifier TS 621 is an electronic measurement amplifier for strain gauge based sensors.The signal tension of the transducers is amplified in such a way, that it is available as astandard signal (10 V at rated capacity of connected sensor) at the outputs V〇ut and l〇ut.Up to two sensors series RFS^ or WTS can be connected to the TS 621. The output signal is theaverage value of both sensor signals.When connecting other sensors, please follow the technical specification in the data sheet TS 621.InstallationWe recommend to install the measurement amplifier TS 621 near the sensors to be used with.The electronic connection is to be executed as per connection diagram on page 10.The signal cable to the measurement amplifier should be shielded and directly beconnected without intermediate terminals, if possible.Start-up and OperationAfter installation of the sensors and connection of the measuring system, please follow theinstructions given below:Kindly check, whether the setting of the coding switches S1 to S4 is corresponding tothe desired configuration. For details see description of options on page 11 to 13.Make sure of the correct supply voltage: 24V DC (19-36V DC).Connect a digital voltmeter with the output clamp V〇ut.
