In this method,the terminal Pand C hasbeen short connected.
This simple methodcan also beadopted to measurevoltage
with the greenwire connected withV connector.
Use volt meterto measure voltageof the commonterminal
to the earth,this instrument cannotbe used tomeasurethat,
it isvery dangerous,because uncertain stateof theterminal
and connecting wire,the voltage maynot be displayed,
which leads toelectric shock ordamage of theunit. This
unit cannot beused to measurethe common powervoltage,
this unit isnot designed forthis operation, whenusing quick
test head tomeasure(measure earth resistanceonly), the
termial Pand C willbe short connectedwhich will lowerthe
input resistance ofthe product.
4. In operation,press PRESS TO TEST key and turn it
clockwise to LOCK position can perform measure
without manual operation.
5. Aftermeasurement, turn theswitch to OFFif the unitis
