Refer to Figure 2-3 to find the maximum RMS current allowed for
given operating UUT voltage
Minimum Capacitance = (0.8% of rated current) / (Operating UUT
voltage * 2 *Pi* Maximum Frequency)
Resistance Resolution 0.001 ohm till 1 ohm
0.01 ohm >1 ohm to 10 ohm
0.1 ohm from >10 ohm to 1000 ohm
1 ohm from >1000 ohm
Inductance Resolution 0.001 mH till 1 mH
0.01 mH >1 mH to 10 mH
0.1 mH from >10 mH to 1000 mH
1 mH from >1000 mH
Capacitance Resolution 1 uF till 1000 uF
10 uF > 1000 uF
