test leads, and adapters) for all measurements. 
•  Do not exceed the Measurement Category (CAT) 
rating of the lowest rated individual component of a 
Product, probe, or accessory. 
•  Do not touch voltages >30 V ac rms, 42 V ac peak, or 
60 V dc. 
•  Keep fingers behind the finger guards on the probes. 
•  Use only current probes, test leads, and adapters 
supplied with the Product. 
•  Connect the common test lead before the live test 
lead and remove the live test lead before the

extended period of time, or if stored in temperatures 
above 50 °C. If the batteries are not removed, battery 
leakage can damage the Product.
