Adopting resistance loop technology, 618-1 provides timely and continuous monitoring on static-proof wrist wrap. 618-1 is capable of monitoring operators exactly.
The ex-works upper limit of earth leakage resistances is stipulated as 800K, while the lower limit is 9M. Thus covering the monitoring on various types of static-proof wrist wraps.
-
Can monitor closely on working status of one operator’s static-proof wrist wrap
-
Generate visible and audible alarm against operator’s safety and status of low-resistance and over-resistance.
-
Monitoring range on operator:
LOW: 800K>R yellow LED glitter and audible alarm
PASS: 800<R<9M green LED light
HIGH: R>9M red LED light and audible alarm -
Accuracy: ±10%
-
Resistance range can be set as per customers’ requirement.
-
Auxiliary power source: 220VAC/50HZ for input and 9-12VDC/500mA for output
