PT Item – Process Calibrator and AC Source – Measure Mode

Resolution and Range – AC Source – Voltage 310 Vrms / Resolution – 0.01 V at 0 ~ 99.99 vrms and 0.1 V at 100.0 ~ 310 vrms
AC Current Source – 2.00 ~ 70.00mA/60.0 ~ 350.0mA/0.300 ~ 3.500A/3.00 ~ 17.5A / Resolution – 0.01 mA ,0.1mA, 0.001A, 0.01 A
Parameter – AC Current (2mA to 17.5A) | AC Voltage (0.2 Vrms to 310 vrms)

DC Voltage -20V – Resolution 100 micro V to 10mV/ DC Current 20 mA – Resolution 100nA to 10 micro A

Participation Criteria – The participating Laboratory should have CMCs coarser than 0.01 to 0.041 % for AC Voltage | 0.1% to 0.12for AC Current | 0.004% to 0.076% for DC Current | 0.035% to 0.001% for DC Voltage

Delivery – Lab code will be delivered within 7 working days

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.
