Enabling and disabling 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 filter circuits are
enabled. When either LPF is enabled, the measurement
speed (response time) will be impacted.
The DC Filter cannot be used when the dual display mode is enabled
where AC and DC voltages are measured.
