Description Once an arbitrary value is specified as a refer-
ence, the relative value against the reference is
displayed. This function is useful to check any
discrepancy from the reference.
1.
Move the function selector
to the desired position and
connect the test leads to the
measurement product.
(example:
V )
2.
Connect the test leads to
the measurement object.
3.
Press the H.AUTO/REL
button for at least 1 second
for the value to be defined
as the reference.
(Example: Press the button at
10 V. "REL" lights up and “0000”
is displayed.)
4.
Measure the voltage again
and read the displayed
value (discrepancy from the
reference).
(The measured value minus the
reference is displayed.)
Checking any discrepancy from the reference (when 10 V is de-
fined as the reference in the voltage measurement)

1 second
Any discrepancy from the reference
(10 V) is displayed. In the case of a
negative value, “-” is also displayed.
The measurement range is fixed to the range that
is active when the
H.AUTO/REL
button is pressed.
If the reference value deviates from the full scale,
O.F is displayed. While O.F is displayed, the Rela-
