Enabling the filter
There are two Filter ( ) options within the design of the
multimeter:
• In AC/AC+DC measurement mode, the Filter works as a
low pass filter and attenuates signals with frequencies of
more than 1 kHz
• In DC measurement mode, the Filter will block AC signals
Only one of the two filters can be in the signal path at any
point in time. The possible scenarios are:
• Only the AC Low Pass Filter is enabled
• Only the DC Filter is enabled
• No Filter in the signal path
The icon appears when either of the LPF circuits are
enabled. When either LPF is enabled, the measurement
speed (response time) will be impacted.
