4102a soft case model
4102a-h hard case model
• the latest circuit design permits the instrument to operate
with the minimum of influence from earth voltage
and earth resistance of auxiliary earth spikes.
• dust and drip proof. (designed to iec 529 ip54)
• earth resistance value can be read directly from the scale.
• designed to meet iec 61010-1 safety standard.
• capable of 卡塔尔世界杯中国足球赛事 earth voltage.
• small and lightweight. shock resistant new case material.
• 2ma 卡塔尔世界杯中国足球赛事 current permits earth resistance tests
without tripping earth leakage current breakers
in the circuit under test.
• lead wire connection to c and p terminals and proper
auxiliary earth resistance can be checked by ''ok'' lamp.
lead wire connection to c and e terminals is good
when ''ok'' lamp is illuminated.
