The Klein Tools CL800 is an outstanding auto - ranging true root mean squared (TRMS) digital clamp - meter. It can accurately measure AC/DC voltage, resistance, continuity, frequency, and capacitance. You can test diodes with the test - leads and measure temperature using a thermocouple probe. One of its remarkable features is the Low Impedance (LoZ) mode, which helps you quickly identify and get rid of ghost or stray voltages. Klein Tools designed this test and measurement product line specifically for electricians, based on years of field research and input from electricians across America. This meter comes with many innovative, time - saving features. What's included? You'll get a carrying case, 41' (1041.4 mm) test leads, 3 AAA batteries, and a thermocouple with an adapter. It has high - level safety ratings like CAT IV 600V, CAT III 1000V, Class 2, and double insulation. It can withstand a 6.6 - Foot (2m) drop. The low battery indicator makes it easy to know when to change the batteries, and the battery compartment is easily accessible. It operates well in temperatures from 32°F to 104°F (0°C to 40°C) and up to an altitude of 6562 - Foot (2000m). It meets the requirements for use in basic and controlled electromagnetic environments such as residential, office, and light - industrial locations.
Using the Klein Tools CL800 is quite straightforward. To measure AC/DC voltage, resistance, continuity, frequency, and capacitance, just connect the test - leads to the appropriate ports and the measurement points. For temperature measurement, attach the thermocouple probe. When using the Low Impedance (LoZ) mode, turn it on when you suspect ghost or stray voltages. Here are some important things to keep in mind. Always make sure the battery is in good condition. If the low battery indicator lights up, replace the 2 AAA batteries right away. Don't use the meter in temperatures outside the range of 32°F to 104°F (0°C to 40°C) or at altitudes higher than 6562 - Foot (2000m). Also, handle it carefully as it can only withstand a 6.6 - Foot (2m) drop. For maintenance, store it in the carrying case when not in use. Clean the meter with a dry cloth regularly. Check the test - leads and thermocouple probe for any signs of damage. If there are any issues, don't use the meter and contact Klein Tools for assistance.
