Additional Functions
Pressing the REL key causes future values to be dis-
played relative to the currently displayed value, which
becomes the reference value.
To reproduce a zero adjust function while measuring volt-
age (mV), resistance, etc., short the test leads to set the
relative value display mode. (This cancels the Seebeck
effect and the effect of wiring resistance.)
1. Display the measured value that you want to set as the
reference value.
2. Pressing the REL key sets the currently displayed value
as the reference value, and displays future values as rel-
ative values to that reference value.
