Status indicator lamps
Each lamp is lit in the following case.
AUTO CKT: When the automatic selection of
equivalent circuit is enabled
COMPRTR: When the comparator is enabled
BUSY: During measurement
CONTACT: When the contact check is enabled
CHECK
BIAS ON: During the DC bias voltage output
SOURCE: When the triggered drive is enabled
SYNC
KEY LOCK: When the key operation is disabled
REMOTE: During remote control
Display
40-character x 2-line LCD display.
1st line: Measured value (primary and secondary
parameters) and measurement frequency.
When the comparator is enabled, the comparison result
is also displayed.
(▲: > Upper limit, ▼: < Lower limit)
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 is
used for the setting menu.
Status (2nd line)
RANGE: Auto / Hold and measurement
range
SPEED: FAST / MED / SLOW, etc.
AVERAGE: Averaging count
TRIG SOURCE: INT / MAN / EXT, etc.
CORRECTION: Op (OPEN)

Measurement
ground terminal
It is connected to
the enclosure, and
used to shield DUT.
Measurement Terminals
BNC connector comprising a set of 4-terminal-pair connected to
the device under test (DUT).
H
CUR
: Outputs signals to drive the DUT.
H
POT
, L
POT
: Measures the voltage applied to the DUT.
L
CUR
: Measures the current flowing in the DUT.
Connect all external conductors (shields) of 4 cables.
SHIFT key
Enables the secondary functions written above
each key.
LOCAL key
Restores local operation from remote state.
