AMPERES: Check with "clamp-on" type of ammeter amprobe. Clamp around one of the "hot" power leads going to the kiln from your power supply. Some kilns are equipped with a flat type power cord including two power #6 wires and a #8 ground wire. Separate one of the outside heavy gauge wires away from a section of the cord sufficiently to allow the "clamp-on" ammeter to be properly clamped around this "hot" cable. Take care not to penetrate the insulation exposing the copper wire. Make sure power is off when separating. The amperes per section can then be measured: Add readings together to obtain total amperes and compare to the nameplate amps. The above data may indicate the problem area. If cord supplied is of the round type you can do the above separation on the intermediate cord that goes between the Dawson Kiln Sitter and the instrument panel.
