Cautions during Use
• Follow instructions in 'Cautions during Use' .
Otherwise, it may cause unexpected accidents.
• When the counter is operating, in case of contact input, set count speed to low speed
mode (1 cps, 20 cps, 30 cps) to operate. If set to high speed mode (1 kcps), counting
error occurs due to chattering.
• Keep away from high voltage lines or power lines to prevent inductive noise. In case
installing power line and input signal line closely, use line filter or varistor at power line
and shielded wire at input signal line.
Do not use near the equipment which generates strong magnetic force or high
frequency noise.
• This unit may be used in the following environments.
- Indoors (in the environment condition rated in 'Specifications')
- Altitude max. 2,000 m
- Pollution degree 2
