MEASUREMENT OPERATION
16
Note
In each range, the Meter has an input impedance of 10M
Ω
except for the mV
range which has an input impedance of 3000M
Ω
. This loading effect can cause
measurement errors in high impedance circuits. If the circuit impedance is less
than or equal to 10k
Ω
, the error is negligible (0.1% or less).
For GDM-397: When measuring mV, you must press RANGE manually to enter
mV range.
When voltage measurement has been completed, disconnect the testing leads
from the DUT and remove the testing leads from the input terminals of the
Meter.
