The field technician needs ruggedness, small size, ease of use, and versatility. The LT series low cost meters are well-done versions of far east designed and manufactured meters. The LT series is aimed at price-conscious field service technicians. All the Fieldpiece accessories work with the LT series. Fieldpiece supplies only manual ranging meters.
Manual rangers are more versatile and can be safer for use in the field than autorangers.
To use a manual ranger, the user must consider the voltage level he is about to measure before he touches the test point. Autorangers can help technicians develop a habit of hooking up and looking at the display before he considers how high the voltage might be. Autorangers are often more convenient to use in the lab because of the wider range of measurement values and the lower voltages most often tested.
