ABSTRACT:
Electronic wheel-type area measuring machine has manual or automatic operating means, arranged to emit, at a predetermined point in the machine cycle, a test start signal, the operating means includes test means, which upon receipt of the test start signal, feeds signals to computing means of the machine until the computing means registers a predetermined number whereupon a stop signal is emitted. The test means has duplicate computing means which also receives the test signals until the stop signal is emitted, whereupon the number of signals received by the duplicate computing means is compared with the predetermined number and an alarm signal is given if the number recorded by the duplicate computer means differs by more than a predetermined tolerance from the predetermined number. The counter check system also preferably provides a visual test on a visual test display unit and an output printer.
