Mathematical Operation
Mathematical operation consists of five main functions, statistics, limit value, dB, dBm, and
relative operations. The Mathematical operation functions are available for voltage, current,
resistance, capacitance, frequency/period, and temperature measurements, where dB and
dBm operations are available for voltage measurements only.
