ISO17025 Calibration and Verification

Every PPA5500-TE is supplied with a comprehensive UKAS ISO17025 certificate, featuring power calibration at a range of power factors from unity to 0.01, as well as a UKAS Traceable calibration certificate up to 2MHz. N4L have developed a number of bespoke power calibrators in order to verify the accuracy of every power analyzer supplied over its entire frequency range, this is surprisingly uncommon within the instrumentation industry. Furthermore, development of an ISO17025 (UKAS) accredited Closed Loop Calorimeter in partnership with Oxford University (UK) has verified the performance of the N4L custom designed power calibration rigs with a very low uncertainty level, providing absolute confidence that the wide band performance of all N4L power analyzers is market leading.

Calibration Options

1. Standard Recalibration – Included with new instruments – Included with RMA Calibration
Wideband calibration (DC-2MHz) with optimisation of measurements on all ranges over the complete instrument bandwidth. Traceable to UKAS but not ‘accredited’.
4. UKAS IEC61000 H+F Calibration – Optional with new instruments or RMA calibration
UKAS accredited calibration of PPA55x1 series units that includes all prevailing type test protocols for fully compliant Harmonic and Flicker testing.
This option can only be specified in addition to option 1 and option 2 calibration.
2. UKAS (ISO17025) Calibration – Included with new instruments – Optional with RMA Calibration
UKAS Accredited calibration of Voltage, Current, Phase (PF) and Power on all ranges from 55-850Hz.
In addition to the calibration certificates, the PPA will be fitted with a UKAS calibration label. This option can only be specified in addition to option 1.

5. PPA55xx-TE Calibration – Included with PPA-TE order – Optional with RMA Calibration
UKAS calibration that includes a series of low power factor tests down to 0.01 PF over the frequency range of 16-450Hz.
This option can only be specified in addition to option 1 and option 2 calibration

3. System Calibration – Optional with new instruments or RMA calibration
UKAS accredited calibration of a PPA together with an external sensor.
This option is separate to option 1 & 2 which must both be specified in addition when system calibration is required.
Note: This is end-to-end calibration of the of the PPA+sensor ‘system’ at nine N4L defined test points. (3 current levels @ 3 different frequencies)
6. UKAS calorimeter power calibration – Optional with new instruments or RMA calibration
UKAS accredited power calibration via calorimetry. Available at customer requested frequency(s) and with sinusoidal or harmonically distorted wave shapes within a frequency range of 45Hz to 2MHz.
This option can only be specified in addition to option 1 and option 2 calibration
