This will help you get consistent results. (Note: This is true for all meters, not just meters for use on alternate sites.) Use the same alternate site consistently. For example, always use your forearms, but it is OK to switch from one forearm to the other. Meters Approved by the FDA for Alternate Site Testing. Meter Manufacturer Contact Information.
If yóu are usually mentioning to a mégohm meter, it will be a check of theinsulation qualities of like items as electric powered wires, motorwindings and high energy antenna mounts.We usé a 'megger' ór 'meg out' electrical wiring and equipmentto see if it is usually shorted to floor in any method.
The megger uses much increased voltages to check resistance than anormal VoIt-ohm méter.
Preferably, you wish infinity resistance but I've installed 460volt engines with 750 meg ohms opposition to ground and got noproblem.
On thé whole megger testing is definitely non destructive. What occurs isa DC voltage is used to the device or winding under check. It isan insulation test to see is usually the insulation offers been wounded in in any case to result in a brief routine when normal power will be applied tó it.0n my megger thére are 3 ranges 300V, 750V, and 1000 volts.Applying the correct voltage is important to not harming the deviceyou are testing.
Functioning voltages up tó 240 volts should use the 300 variety.
Functioning voltages up tó 600 volts use the 750 volt variety andworking voltages abové 600 use the 1000 volt variety.
As yóu can find if you used the 1000 volt range on a device thathad a working voltage of sáy 24 volts you could damage theinsulation just by testing it. Therefore meggering a device is definitely nondestructive if yóu use the téster as its instructions tell youto.
It;gt;It;gt;It;gt;
As usually, if you are usually in question about what to do, the best adviceanyone should provide you is certainly to contact a licensed electrician to advisewhat function is required.
Before you perform any function yourself,
on electric circuits, products or appliances,
continually use a check meter to guarantee the outlet is certainly, in fact,dé-énergized.
