A fluid-operated gage is provided for determining acceptability of workpieces and such gage uses a pair of classifying devices to classify gaging signals into an acceptable range and indicators operatively connected to the classifying devices to indicate the character of each workpiece being checked. Limit control means is provided causing each classifying device to provide an oscillating signal to its associated indicator within a predetermined band once its limit is reached to enable precise setting of each classifying device.
