... SP 400-BLUE SCALING Two external resistors Ra and Rb may be used to alter the full scale reading (FSR) of the meter - see table. The meter will have to be re-calibrated by adjusting the calibration potentiometer on the rear of the module. APPLICATIONS Do not connect more than one meter to the same power supply if the meters cannot use the same signal ground ...
