Performing Demagnetizing And Zero-Adjustment - Iwatsu SS-520 Instruction Manual

4 Wait at least 30 minutes after turning on the device.
Immediately after power is supplied, offset drift may
increase due to the effects of self-heating of the device
and other factors. To ensure accurate measurement, wait
at least 30 minutes after turning on the device before
performing measurement.

Performing Demagnetizing and Zero-Adjustment

Always carry out demagnetizing and zero-adjustment before
measurement.
The demagnetizing and zero-adjustment process takes
about 20 seconds.
What is "Demagnetizing"?
Demagnetization is a function used to eliminate the
magnetic charge of the magnetic core, which can result from
turning the power on and off, excessively large input, or
other factors.
What is "Zero-adjustment"?
Zero-adjustment corrects offset voltage fluctuations caused
by factors such as the device-specific characteristic offset
voltage and temperature variations.
