Conforms to EN61010-1/IEC61010-1 (pollution degree2/overvoltage category III)

Conforms to VDE0106/P100

Note: 1. Only PNP/NPN universal DC voltage input models (-H models) have a backlight.

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

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

4. 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".
