Amp Settings
(1) CH ............................ Indicates the channel number.
(2) AMP .......................... Displays the type of amplifier installed
V : WR3-V (Voltage) amp
M : WR3-M (Multi-input) amp
DCB : WR3-DCB (DC strain) amp
FV : WR3-FV (Frequency-to-voltage conversion) amp
(3) Input.......................... Selects the input coupling status. The available settings vary with the type of amp
installed.
Available Settings: WR3-V amp
Off : No signal input is accepted.
AC : Used for measuring an alternating-current component of signal input that
also contains a direct-current component.
DC : Used for measuring direct-current voltage.
GND : Measures the 0-V line instead of measuring changes in the signal input.
CAL : Generates a calibration voltage that is 1/2 full scale of the currently
selected range instead of measuring the input voltage.
Available Settings: WR3-M amp
Off : No signal input is accepted.
AC : Used for measuring an alternating-current component of signal input that
also contains a direct-current component.
DC : Used for measuring direct-current voltage.
TEMP : Used for measuring temperature.
GND : Measures the 0-V line instead of measuring changes in the signal input.
CAL : Generates a calibration voltage that is 1/2 full scale of the currently
selected range instead of measuring the input voltage.
Available Settings: WR3-DCB amp
Off : Select this setting if you do not wish to perform measurement.
DC : Select DC to measure the strain sensor's output voltage in DC coupling
status.
ZERO : Select ZERO to check the zero-point position
CAL+ : Select CAL+ to check the "+1/2 full-scale" position of the measurement
range.
CAL– : Select CAL+ to check the "–1/2 full-scale" position of the measurement
range.
