1、The output signals may be resistance signals( resistance value can be set by yourself) or voltage signals.
2、The D.C. resistance of each phase is also checked against the calculated resistance value for the stator and for balanced resistance between each phase.
3、The insulating layer thermal conductivity value of table1 is calculated by the Al-Substrate CCL thermal resistance value.
4、Method in reducing the shared grounding resistance value in the tall building;
5、Test and mark the resistance value of the old elements having been replaced (with voltmeter and ammeter) and distribute them in low temperature area.
6、During the working,the voltage should be increased to maintain the furnace normal temperature becauise the resistance value will go up gradually caused y the oxidation of element.
7、If in the regulation of the resistance value of the process, hand beating phenomenon, the existence of the fault of bad contact potentiometer.
8、If the heading element is much damaged or its resistance value increases too much and cannot reach the furnace temperature, it is better to replace the heating elements with mew ones.
