Function setting status lamps
These lamps indicate the setting status.
Function lamps light up when set to a value other than the default setting.
SYNC
Lights up when the synchronization source is set to I or DC
(the default setting is voltage: U). (p.48)
TIME OUT
Lights up when the synchronization detection timeout is set
to 1 sec. or 10 sec. (the default setting is 0.1 sec.). (p.54)
FREQ
Lights up when the zero-cross and frequency measure-
ment filter setting is set to 100 Hz, 5 kHz, or 100 kHz (the
default setting is 500 Hz). (p.50)
AVG
Lights up when the number of averaging iterations is set to
a value other than the default value of 1. (p.56)
VT
Lights up when the VT ratio setting is set to a value other
than the default setting of 1. (p.58)
CT
Lights up when the CT ratio setting is set to a value other
than the default setting of 1. (p.58)
SENSOR
Lights up when the current input method setting is set to
TYPE.1 or TYPE.2 (current sensor input) (the default set-
ting is OFF [current value direct input]). (p.38)
RANGE SEL
Lights up when either the voltage measurement range or
current measurement range is set to OFF. (the default set-
ting is range select: ON). (p.46)
Lights up when any of the zero-cross threshold levels is set
to a value other than the default setting of 1%. (p.52)
HRM LIMIT
Lights up when the harmonic analysis order upper limit is
set to a value other than the default value of 50. (p.76)
SYNC. OUT
Lights up when the synchronized measurement I/O setting
is set to OUT (Master). Flashes with external synchronized
signal input when set to IN (Slave). Turns off when set to
OFF. (p.78)
D/A Lights up when the 7 channels of D/A output are set to val-
ues other than their default values. (p.88)
PW3335-02 PW3335-04
These lamps indicate the instrument’s overall setting status.
They light up when the corresponding function is ON.
KEY LOCK Lights up when key operation is disabled. (p.109)
REMOTE
Lights up when the instrument is in remote operation mode.
(p.133)
AUTO
Lights up when the voltage or current measurement range
is set to auto range (the default setting is auto range OFF).
(p.43)
B
Indicates the B 20 A range used in auto-range integration
mode. Lights up when a range is selected while integration
is stopped. (p.61)
When the VT and CT lamps are lit up (particularly when the VT ratio and CT ratio are
set to values less than 1), a voltage or current greater than the displayed measured
value may have been input to the instrument. To prevent an electrical accident or
short-circuit, do not unnecessarily touch the instrument’s input terminal or the mea-
surement lines.
