Demagnetizing And Zero Adjustment - Iwatsu SS-540 Instruction Manual

2.2 Demagnetizing and Zero Adjustment

Notes
⋅ Immediately after the power is turned on, this instrument
will heat up, in some cases causing considerable offset
voltage drift. This should stabilize almost completely in
about thirty minutes.
⋅ When conducting continuous measurement, please note
that the offset voltage will drift due to the ambient
temperature, etc.
1. Set the oscilloscope input to GND and adjust the trace to
the zero position.
2. Set the oscilloscope input coupling to DC.
3. Plug the output connector on this instrument into the input
terminal on the oscilloscope and check to make sure it is
locked securely in position.
