–Auto Range
Enable or disable the auto input range.
If auto range is enabled, each analog channel input range is determined automatically, based on the level of the input
signal. If the input signal level changes beyond the ranging threshold, auto range will cause the input ranging circuits to
move up or down for a proper ranging.
If auto range is disabled, you can set a fixed input voltage range for each analog input channel.

If Track 1st Ch is enabled, all the other channels will be set to follow the channel 1 range setting. Any changes made to
channel 1 range setting will be reproduced in the other channels. Disable the Track 1st Ch to set the individual
channels.
– Voltage Range
