Measurement of Input Signal Voltage with Pen Recorder
To obtain input signal voltage V from the waveform recorded by the pen recorder, use the following equation:
Pen recorder input level (V/cm) x Recorded amplitude (cm)
V(v) = x Write input level (V/div)
0.2
(V/div)
Measurement of Input Signal Time with Pen Recorder
To obtain write signal time T from the waveform recorded by the pen recorder, use the following equation:
Pen recorder feed speed (sec/cm)
T ( s e c / c m ) = x Write speed (sec/div)
Readout speed (sec/div)
FREE RUN function
T h i s function is used to automatically repeat store and read
operations. T h e period for w h i c h the input waveform data
is stored in the memory can be varied from about
A
to
20
seconds w i t h the D I S P L A Y T I M E knob; this is convenient
when it is necessary to observe consecutive phenomena
without observer intervention.
By pulling the D I S P L A Y T I M E knob ( R E A L position), the
F R E E RUN functions.
Depressing the D I S P L A Y T I M E knob resets the free run
function and sets the R E A L mode.
Pressing and holding the write S T A R T button for one
repetition of the store and read input w a v e f o r m data cycle
temporarily suspends the automatic free run function in the
memory read state. Press and then pull the D I S P L A Y T I M E
knob, or set the D I S P L A Y MODE s w i t c h to the M E M O R Y
(or D U A L ) position, then to the R E A L position to restart the
automatic free run function.
Note:
The F R E E RUN function will not a l w a y s start by turning
on the P O W E R s w i t c h w i t h the D I S P L A Y T I M E knob in
the pull out position.
