Measurement Compatibility and Error
Messages
Channel 1 or Channel 2 Voltmeter measurements, expept DC, cannot be
made when the signal is larger than the range of the B trigger level. The dis­
played error message is O U C H -T U R N VOLTS/DIV CCW.
NOTE
When making DC measurements, overranged signals will not
cause an error message to be displayed but can display incorrect
voltage readings . To obtain accurate DC readings keep the
waveform within the graticule limits.
