Best DPF Series Quick Start Manual

DPF SERIES
Dear clients, thanks for choosing IBEST DPF Series frequency-tacho-linespeed meter! Before installing and operating the products, please read
this instruction manual carefully. For any questions, please contact our sales people immediately.
! SAFETY CAUTIONS:
● Make sure the power is at "OFF" status before connecting the wires to avoid electric shock and strictly follow the connection diagram
given out by the factory.
● Make sure the power OFF when cleaning the product.
● Working beyond the stated power supply (90-250V AC) is prohibited so as to avoid damage to the product or cause fire.
● Make sure the OUTPUT RELAY is used at the rated load and electrical life, if the contact of the output reply works against the electrical
life, it may melt or burned or even cause fire.
● Install power switches and circuit breaker for power safety.
! STOCK AND MAINTAINENCE NOTICE:
● Try to avoid interfere headstream, input signals cable should not be too long, better to use twisted-pair shielded cable, shielded layer
connected with singals low end.
● Prevent from violent vibration, shock and incursion of heavy dust.
● Stock long terms at 0~50
● When instrument power supply has noises, paticularly when inductive voltage caused by relay or contact devices switch ONand OFF
result in serious interference, must configure filter or rheostat or noises absorber.
