Specifications

■

General

Note: 1.

Only PNP/NPN universal DC voltage input models (-H models) have a backlight.

The frequency range for an AC voltage is 50 to 60 Hz.

“-hours”, “-d-h”, “-h-m”, and “-h-m-s” labels are included.

Zero suppression: Zeros are not displayed to increase readability. For example, "000008.2" is displayed as "8.2" if zero suppression is

set. If the range is set to 3999d23.9h, the value is "008.2".
