Characteristics

Overflow/underflow display	Overflow: 1[][][] Underflow: -1[][][]
Input signal	DC voltage
A/D conversion method	Double integral method
Sampling period	2.5 times/s
Display refresh period	2.5 times/s
Max. displayed digits	3 1/2 digits (+1999)
Display	7-segment red LED
Decimal point display position	By short-circuiting terminals
Sign display	"-" is displayed automatically with a negative input signal.
Overflow/underflow display	Overflow: 1[][][] Underflow: -1[][][]
