• TABLE 6: NORMAL MODE
TIMING signal
When the TIMING signal is ON, ‘TG’ indicator turns on,
however the signal is invalid. Measures continuously.

HOLD signal
While the HOLD signal is ON, the display reading is held
at the measured value at the falling edge of the signal,
and the TIMING, S-TMR and ZERO signals are invalid.
Scaling error
During the scaling error, data measuring continues.
However the display shows the scaling error. If the
HOLD signal turns ON during the scaling error and is
maintained after the scaling error is canceled, the display
reading changes to the measured value at the falling
edge of the signal.
RESET signal
Resets the measured data with the RESET signal ON
(no measurement).
DC output
Proportional to the display reading. For no measured
data, the value is 0%.
• TABLE 7: SAMPLING HOLD MODE

Data is measured at the falling edge of the TIMING
signal.

HOLD signal
While the HOLD signal is ON, the display reading is held
at the measured value at the falling edge of the signal,
and the TIMING, S-TMR and ZERO signals are invalid.
Scaling error
Stops data measuring.
RESET signal
Resets the measured data with the RESET signal ON
(no measurement). The TIMING signal is invalid.
DC output
Proportional to the display reading. For no measured
data, the value is 0%.
• TABLE 8: PEAK HOLD MODE
TIMING signal
While the TIMING signal is ON, the MAX value within the
period is measured and stored, and is established at the
rising edge of the signal.

While the HOLD signal is ON, the display reading is

invalid.

Resets the measured data with the RESET signal ON

• TABLE 9: VALLEY (BOTTOM) HOLD MODE

While the TIMING signal is ON, the MIN value within the
