255, and then press X1 to finish inputting.
Vm:OFF：Move the cursor to it, ON and OFF will be displayed in the soft key zone.
The measurement voltage across DUT will be displayed in the <MEAS DISP> page
when ON is selected; when OFF is selected, it will be turned off.
Im:OFF：Move the cursor to it, ON and OFF will be displayed in the soft key zone.
The measurement current through DUT will be displayed in the <MEAS DISP>
page when ON is selected; when OFF is selected, it will be turned off.
DEV A:OFF：Move the cursor to it, OFF, ABS and % will be displayed in the soft
key zone. When OFF is selected, the primary display value is the primary
measurement value; when ABS is selected, the primary display value is the primary
measurement value minus the primary reference value; when % is selected, the
primary display value=[(the primary measurement value-the primary reference
value)/ the primary reference value]*100%.
DEV B:OFF：Move the cursor to it, OFF, ABS and % will be displayed in the soft
key zone. When OFF is selected, the secondary display value is the secondary
measurement value; when ABS is selected, the secondary display value is the
secondary measurement value minus the secondary reference value; when % is
selected, the secondary display value=[(the secondary measurement value-the
secondary reference value)/ the secondary reference value]*100%.
REF A /REF B: Primary and secondary reference values. Move the cursor to it,
INCR++, INCR+, DECR-, DECR-- and MEAS will be displayed in the soft key
zone. When MEAS is selected, primary and secondary measurement values of the
current DUT will be displayed in REF A and REF B. Press INCR++, INCR+,
DECR-, DECR-- keys and the value will be increased and decreased. You can also
input the desired value through the numerical keyboard and press the corresponding
soft key to confirm.
LINE:50Hz：Move the cursor to it, 50Hz and 60Hz will be displayed in the soft key
zone. User should adopt a power source whose frequency is identical to that of the
inlet power supply, thus to decrease the measurement error causing by the noise of
power frequency.
Delay:0ms：Move the cursor to it and input the desired value through the numerical
keyboard ranging from 0 to 60s, and then press X1 to finish inputting.
3.4.1 TRIG
TH2523 has four trigger modes: INT (internal trigger), MAN (manual trigger), EXT (external
trigger) and BUS (bus trigger).
When Trig is set to the INT mode, TH2523 will automatically make continuous measurement.
