3.8 MEASURING FREQUENCY
1. Connect the black test lead to the COM jack and the red test lead to the V
Ω
jack.
2. Set the rotary switch at Hz position and connect test leads across the source or
load under measurement.
NOTE:
1. Reading is possible at input voltage above 10Vrms, but the accuracy is not
guaranteed.
2. In noisy environment, it is preferable to use shield cable for measuring small signal.
