The machine is specifically designed to measure load on bourdon tube type load gauges which are calibrated against certified results. The load gauges are placed with a maximum load pointer. In the electrically operated pumping units, load gauges have safety micro switches to switch-off the motor when the load approaches the maximum capacity of the gauge, avoiding any over loading. Relays are also fitted to ensure that the motor does not restart on its own after a power breakdown. The electrically operated pumping units are provided with a control knob to adjust the pace rate which can be effectively controlled by an experienced operator during testing period in accordance to the progress of the load gauge reading. The electrically operated pumping units are also fitted with hand operated pump to operate the machine in case of electrical brake down.
