Gate Time
Gate time (also called Aperture Time) applies to FREQ or PERIOD function. It decides
the resolution of low-frequency measurement. The longer the gate time is, the
higher the resolution of the low-frequency measurement is and the slower the
measurement is, and vice versa.
When the current measurement function is FREQ or PERIOD, enter the fourth step of
the channel configuration guide, use the up/down direction keys to select GateTime
and use the left/right direction keys to select “1ms”, “10ms”, “100ms” or “1s”. The
default is “100ms”.
Channel Delay
Channel delay is applicable to all the multiplexer channels. Channel delay is the time
interval between two neighboring channels during a scan as shown in the figure
below. During the scan, the instrument immediately disconnects the previous
channel and closes the current channel after finishing measuring the previous
channel. The instrument starts the next measurement after the specified channel
delay time has been reached.
When the current channel is a multiplexer channel, enter the fourth step of the
channel configuration guide, use the up/down direction keys to select Delay and use
the left/right direction keys to select “Auto” or set a specific delay value.
 Auto
In auto mode, the instrument calculates the channel delay according to the
function, range, integration time and AC filter of the current channel
automatically. At this point, the channel delay time changes each time the
configuration of the current channel is changed.
