Output Signal
BCD Output • BCD positive logic signal that represents measured values
Measured value is output every 20 ms when the MOVE averaging mode
(number of measurements for averaging: 16 to 1,024) is set, or every
"2.5 ms x number of measurements for averaging" when the SIMPLE
averaging mode is set.
• When the measured value is negative, "1011" is output as the 10 3 digit.
Input Signal
External Trigger Enable Input
(ETE IN)
Input Level Output
ETE IN
HIGH
(Input level is HIGH
even when this pin is
open.)
Measured value is output every 20 ms
when the MOVE averaging mode
(number of measurements for averag-
ing: 16 to 1,024) is set, or every "2.5 ms
x number of measurements for averag-
ing" when the SIMPLE averaging mode
is set.
LOW
Measured value is output only when
EXT TRIG IN signal is received.
• When ETE IN is pulled low inputting EXT TRIG IN signal allows measured
values to be output at the desired timing.
• Pull ETE IN low, if STROBE OUT signal cannot be received by external
equipment when ETE IN is pulled high.

Timing Diagram
Strobe Signal (STROBE OUT) Negative logic signal with pulse width of approx. 500 µs that represents
output timing of BCD signal
• When ETE IN is pulled low:
• When ETE IN is pulled high:
0.1 µs min.
