Note
• The counter unit's least significant digit (rightmost digit) is
the first digit.
The letters in parentheses have the following meanings
A: 1, B: 2, C: 4, D: 8.
• Note that the signal arrangement differs from the LT10/
LT11 series.
BCD output
In the mode, mode
(See "8-2. I/O timing".)
When DRQ has been received from at #º, and when the
READY output at #¡ goes "L" (ON), the BCD data is output.
In the mode
The data is output at the output time interval which was set
as the initial setting even when DRQ is not input.
• Output logic
True logic or false logic can be selected.
(See "5-1-2. BCD model")
True logic : "L" (ON) is "0".
"H" (OFF) is "1".
LT20A / LT30 Series
1st digit
• Output format
Whether to hold the BCD output data or to assume
high-impedance when there is no DRQ signal input can
be selected.
(See "5-1-2. BCD model")
In the mode, the unit cannot enter the high-
impedance state.
Measuring mode selection input
Current value, maximum value, mimimum value, peak-to
peak value can be selected.
