Display
40-character

2-line LCD display.
1st line: Measured value (primary and secondary
parameters) and measurement frequency
When the comparator is enabled, the comparator result is
also displayed.

2nd line: Status, DC bias voltage, measurement signal level
The status can be switched to IV monitor, etc.
When detailed setting is made, the entire display switches
to the setting menu.
Status (2nd line)
RANGE: Auto / Hold and
measurement range
SPEED: FAST / MED / SLOW, etc.
AVERAGE: Averaging count
