This chapter describes calibration procedures when the AM012 calibrator is used with:
AM11(in Section 4.1), ADMAG AE, ADMAG CA(in Section 4.2), ADMAG SE(in
Section 4.3), AM12, AM100A/B, AM200A/B(in Section 4.4), YMA11(in Section 4.5),
Compact YEWMAG (CYM)(in Section 4.6), AXFA11(in Section 4.7), AXFA14 and
AXF integral flowmeter(in Section 4.8).
Refer to each section to perform the desired calibration.
IMPORTANT
• As a rule, calibration of the converter should be implemented in a maintenance service
shop where the necessary tools are provided.
• The amplifier unit contains sensitive parts that may be damaged by static electricity.
Excercise care so as not to directly touch the electronic parts or circuit patterns on the
board, for example, by preventing static electrification by using grounded wrist straps
when handing the unit. Also take precautions such as placing a removed amplifier unit
into a bag with an antistatic coating.
4.1 When AM012 is used with AM11
4.1.1 Interconnections
Turn the AM11 power OFF.
Disconnect the signal and excitation wirings for the AM11.
Connect the signal and excitation cables to the AM012.
Connect the power and ground cords to the AM012.
Proceed to 4.1.2 Checking Procedure.
(Ground the AM012 to prevent it from being affected by external noises. After turning the power on,
let the instrument warm up for at least ten minutes.)
