3.4 Test Range (Function)
Model 6050 performs four functions.
1. LOOP.....Loop impedance tester
2. RCD.......RCD tester
3. Uc..........Contact voltage tester
4. PSC.......Prospective short circuit current tester
3.5 Applied Standards
Instrument operation: IEC/EN61557-1,3,6,10
Safety: IEC/EN61010-1 CATⅢ(300V)-instrument
IEC/EN61010-031 CATⅢ(600V)-test lead
Protection degree: IEC60529(IP54)
3.6 Features
Model 6050 has the following features:
● Wiring check
Three LEDs indicate if the wiring of the circuit
under test is correct.
● Over temperature
protection
Detects overheating of the internal resistor and
of the current control MOS FET displaying a
warning symbol ( ) and automatically halting
further measurements.
● Phase angle
selector
RCD test can be selected from either the
positive (0° ) or from the negative (180°) half-
cycle of voltage. At both polarity, test minimum
(best) and maximum (worst) trip times.
● Auto data hold
Measured result is being held until any switch
other than MEM switch is pressed. Instrument
is back to voltage measurement mode when
applying voltage again during data hold
function is operated.
