n П
O'FLO — When measuring the width of an input signal
that exceeds five
seconds
in duration
, the
overflow
message
"
O'FLO " will
be
displayed on
the
readout .
proximately
one
second ,
it
will display
the
forward
voltage
drop
of
the
device .
C
Fd - In Ohms
mode “ Fd " will
be displayed
on the left
side of the readout to indicate that a forward voltage
drop
is
being
displayed .
no ALT H
- With the
instrument
in A
HORIZONTAL
MODE ( non -
delay ) , the
readout will
display a " no Alt
H " when either
the A TIME
or DLY TIME
mode is
selected .

1
Probe - ? - When
the
temperature probe
exceeds its
internal resistance limits the readout will display
“ ProbE- ? ” to indicate that the temperature probe is
either
faulty or
disconnected
from the
Multimeter
input
connectors .
no A trig
-
With the
A TIME
mode
and
either the
ALT
or B HORIZONTAL MODE selected , the readout will
display
" no A
trig " when
either the A
Sweep is not
running , or is too slow . This message is also displayed
with the instrument in A HORIZONTAL MODE and
either the FREQ or PER mode selected , and the CTM
is not receiving a trigger signal .
Short -- In Continuity mode the readout will display
" Short " when the measured resistance is less than
5.0 N.
no b trig
— When
either the
A
TIME or DLY
TIME
mode and either ALT or B HORIZONTAL MODE is
selected with the A Sweep triggered and the B Trigger
circuit not receiving a trigger signal in delay mode , the
readout will display “ no b trig ” . This message is also
displayed with
the
instrument in either
ALT or
B
HOR
IZONTAL MODE and either the FREQ or PER mode
selected , and the CTM is not receiving a trigger signal .
OUCH
- The
word “
OUCH " is
displayed when
the in
put
voltage
to the
multimeter
inputs
is
500 volts
or
more in DCV
mode , and
350 volts or
more in AC
RMSV mode . In CH 1 V mode , the word “ OUCH ” is
displayed if overranged .
dc - In CH 1 V mode with Channel 1 Input Coupling
switch in GND or DCV position , " dc " will be displayed
on the left
side of the
readout .
了
OPEN — The readout will display “ OPEN ” with the
CTM in either Ohms or Continuity mode ( AC RMSV
and TEMP buttons pressed in ) under the following
conditions ; in 2 mode one or both test leads discon
nected or when resistance exceeds 1.99 G1 , in Conti
nuity mode when the resistance equals or exceeds
5.0
12 .
AC - in CH 1 V mode with Channel 1 Input Coupling
switch in AC RMSV position , " AC " will be displayed on
the left side of the readout .
p - In CH 1 V Relative Reference mode , " p " will be
displayed
on
the
right
side of the
readout
.
diodE — In Resistance / Semiconductor mode the read
out will momentarily display " diodE " , and an audible
tone will be generated if the device being measured is
a
forward -
biased
semiconductor
junction . After
ap
no dELTA - When in A TIME mode with the measure
ment intensified zone ( moved by rotating the A TIME
position control ) dialed off the right end of the trace ,
the readout will display " no dELTA ” .
