TIMING signal
While HOLD signal is ON, the display reading is held at the measured value at
the falling edge of HOLD signal, and TIMING, S-TMR and ZERO signals are in-
valid. HOLD signal
During Scaling Error, data measuring continues. However the display shows
Scaling Error. If HOLD signal turns ON during Scaling Error and is maintained
after the Scaling Error is canceled, the display reading changes to the
measured value at the falling edge of HOLD signal.
Scaling Error
RESET signal
Proportional to the display reading. When RESET signal is ON, the value is
0%.
DC output
Data is measured at the falling edge of TIMING signal.
While HOLD signal is ON, the display reading is held at the measured value at
the falling edge of HOLD signal, and TIMING, S-TMR and ZERO signals are in-
valid.
Stops data measuring.
Resets the measured data and TIMING signal is invalid.
Proportional to the display reading. For no measured data, the value is 0%.
While TIMING signal is ON, the maximum value within the period is measured
and stored.
While HOLD signal is ON, the display reading is held at the last measured val-
ue at the falling edge of HOLD signal, and TIMING, S-TMR and ZERO signals
are invalid.
Stops data measuring.
Resets the measured data and TIMING signal is invalid.
Proportional to the display reading. For no measured data, the value is 0%.
While TIMING signal is ON, the minimum value within the period is measured
and stored.
While HOLD signal is ON, the display reading is held at the last measured val-
ue at the falling edge of HOLD signal, and TIMING, S-TMR and ZERO signals
are invalid.
Resets the measured data and TIMING signal is invalid.
Proportional to the display reading. For no measured data, the value is 0%.
While TIMING signal is ON, the difference between maximum and minimum val-
ue within the period is measured and stored.
While HOLD signal is ON, the display reading is held at the last measured val-
ue at the falling edge of HOLD signal, and TIMING, S-TMR and ZERO signals
are invalid.
Stops data measuring.
Resets the measured data and TIMING signal is invalid.
Proportional to the display reading. For no measured data, the value is 0%.
