– When calibrating the weighing unit, it is possible to make calibration report which complies with the GLP, GMP or ISO standard. – There is a certified temperature calibrator (accessory AX-MX-43, only for MX-50) to check or adjust the calibration of the pan temperature for precise temperature control and traceability.
AND MX-50/MF-50 Instruction Manual 11.2. Calibration Adjustment of the Weighing Sensor – An OIML Class F1 calibration mass of 20g or 50g can be used for the calibration, however a 20g calibration mass (WTF1-20G) is recommended. Caution – Avoid vibration and drafts that affect the weighing sensor. If affected, the analyser may be unable to calibrate the weighing unit.
Calibration mass SIGNATURE Signature - - - - - - - - 11.3. Calibration of Drying Temperature for MX-50 Sensor pan – The temperature calibrator (accessory AX-MX-43) adjusts the drying temperature on the pan. Put the sensor on the pan and input measurement data at 100°C and 160°C.
AND MX-50/MF-50 Instruction Manual 11.3.1. Operation Sensor Leave no gap Leave no gap 1. Replace the weighing pan with the sensor pan of the temperature calibrator. 2. Bend the sensor wire so it does not touch the heater cover and glass-housing when closing the heater cover.
