Using the Greenlee CM-450 is easy. First, make sure the battery is installed correctly. To measure amperage, simply clamp the jaws around the conductor. For voltage measurement, connect the test leads to the appropriate points. The auto power off feature helps save battery life, so don't worry about leaving it on accidentally. When it comes to maintenance, keep the meter clean and dry. Avoid exposing it to extreme temperatures or moisture. If you need to replace parts, the TSG-3 Sure-Grip Test Leads and TC-5 Carrying Case are available. And always follow the safety guidelines in the manual to ensure safe operation.
