• TABLE 10: PEAK-TO-PEAK HOLD MODE
TIMING signal
While the TIMING signal is ON, the difference between
the MAX and MIN values with-in the period is measured
and stored, and is established at the rising edge of the
signal.

HOLD signal
While the HOLD signal is ON, the display reading is
held at the last measured value at the falling edge of the
signal, and the TIMING and S-TMR 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%.
NOTE
• While the TIMING signal is ON, ‘TG‘ indicator turns on (right figure).
• The HOLD signal is ineffective when the RESET signal is ON.
• Except in the normal mode, the one-shot output is provided every measurement
timing regardless of the display refreshing rate.
• The MAX and MIN values can be reset with the RESET signal ON regardless of
the MAX/MIN display control lockout setting.
• The MAX and MIN values cannot be indicated with the front button control for no measured data.
• The MAX and MIN values are updated at the falling edge of the TIMING signal and indicated with the front button con-
trol in the sampling hold mode.
• The MAX and MIN values while the TIMING signal is ON are indicated with the front button control in the modes except
the normal and sampling hold modes.
• The scaling error in Tables 6 to 10 includes ‘B.ERR’.
