Continuity is the connection between the igniter and the cue on the firing module: a cue is the speaker terminal or port in which the igniters connect to the firing module. Confirming a connection between the igniter and the cue will ensure that your igniter receives the power needed to fire the attached product. The COBRA firing system tests for continuity by sending a small pulse of electricity through the igniter to verify resistance is present. To learn how to check continuity on the 36M or 72M, see What is continuity and how do I test it on my module or 18R2?
You can also check continuity on the 18R2 directly; please see 18R2 Check Continuity for more information.
Local continuity checks on the 36M and 72M are a bit different from a check done from a COBRA 18M firing module. On the 18M you only have one channel and one set of 18 cues. On the 36M you have two channels, two banks of 18, and on the 72M you have 4 channels and 4 banks of 18 cues.
To check continuity on the 36M or 72M you will have to press the change bank button to ensure the module is displaying the relevant information for that specific bank. Once you see the bank and channel on the LCD display you may press the modules test button. The module will now display the continuity for that specific channel and bank.
To continue checking other banks please press the change bank button and repeat.
