Frequency Calibration
Frequency calibration is easier than others; generally just calibrate 2V range is enough.
The frequency calibration procedure is:
1. Press to select AC voltage measurement function, then press Rng+ or
Rng- to set the range as 2V;
2. Press , and select menu button T/C PSW , input password, and set
SecrOff , then select CAL Enter ;
3. Input a sine wave of 1V, 450 kHz into the terminal of Input HI-LO by FLuke 5520A,
and press Gain , finally select Save and exit.
Capacitance Calibration
The way to calibrating Capacitance is similar with AC but a little difference. It also
includes Zero calibration and Gain calibration, but all the input terminals on front panel
are opened. Please refer to the section “AC calibration” about the detailed procedure.
The capacitance calibration input values are shown in table 4-3.
