Recalibration Requirements for Field Meters with Separate Components (XRP-3000 and DSE-2000 kits)
Meter = Sensor (eyes) + Readout Unit (brain)
One does not work without the other, therefore both parts must be calibrated together to have calibration stickers with same date provided – this is CRITICAL for auditors to ensure semi-annual or annual recalibrations are performed properly.
We only recalibrate sensors (single or dual) and then connect the readout unit to verify the microprocessor and software are functioning properly. Once both parts are performed each component will get stickers with same date reflecting appropriate part no. and serial no.
Q: Why must I recalibrate both readout unit and sensor NOW?
A: This has always been the process for ASTM compliance for dated calibration stickers but NOW is a requirement for ISO 17025 accreditation.
