The reading of horizontal angle could reach at least ±2000°00’
00” when
measuring in “
Plate left” or “
Plate right”
mode. The five-seconds reading could
reach at least ±1999°59’
59”

? Error E04 will be shown on the display when measured error every time exceeds
or equals ±30”
during the repeated measurement, go back to step ? .
