PT Item – Digital Multimeter 3 1/2 Resolution(GW INSTEK)

PT Round – PTC/ELTC/DGMM/001

PT Item – GW Instek Make 3 1/2 Resolution Model GDM 532

Parameter – DC Current (1mA to 10A) | DC Voltage (2mV to 1000V) | AC Current (100 µA to 5A) | AC Voltage (50 mV to 980 V)

Participation Criteria – The participating Laboratory should have Estimated Uncertainties > 0.058% to 0.012% for DC Voltage | 0.106% to 0.028% for DC Current | 0.077% to 0.018% for AC Voltage | 0.139% to 0.091% for AC Current

Note: Participation criteria defined above, is based on present NABL practice of ILC, where CMC of reference lab should be superior (smaller measurement uncertainty) than the participant’s CMC. All Participant labs should ensure that the participation criteria have been met while applying for the PT.

The participant lab should not report estimated uncertainty, superior than accredited CMCs for that parameter for PT measurements. If Estimated uncertainty is coarser to accredited CMCs then Estimated uncertainty should be reported by the participant laboratory. 

Registration- Open*(This PT Item has waiting period of 4-6 months due to more no. of participants)
