10.216,5 VDC
This is the 10 Vdc range, 5 1

•
The resolution is stored in volatile memory; the multimeter sets the
resolution to 5 1
⁄
2
digits (for all functions) when power has been off or
after a remote interface reset.
•
The resolution is fixed at 5 1
⁄
2
digits for continuity and diode tests.
•
For dc and resistance measurements, changing the number of digits
does more than just change the resolution of the multimeter. It also
changes the
integration time, which is the period the multimeter’s
analog-to-digital (A/D) converter samples the input signal for a
measurement.
See also “Integration Time,” on page 57.
•
For ac measurements, the resolution is actually fixed at 6 1
⁄
2
digits.
If you select 4
1
⁄
2
digits or 5
1
⁄
2
digits, the multimeter “masks” one or
two digits. The only way to control the reading rate for ac measurements
is by setting a trigger delay (
see page 79 ).
•
For ratio measurements, the specified resolution applies to the signal
connected to the
Input
terminals.
