When measuring voltage, the Meter acts approximately
like a 10 MΩ (10,000,000 Ω) impedance in parallel with
the circuit. This loading effect can cause measurement
errors in high-impedance circuits. In most cases, the error
is negligible (0.1% or less) if the circuit impedance is
10 kΩ (10,000 Ω) or less.
For better accuracy when measuring the dc offset of an ac
voltage, measure the ac voltage first. Note the ac voltage
range, then manually select a dc voltage range equal to or
higher than the ac range. This procedure improves the
accuracy of the dc measurement by ensuring that the
input protection circuits are not activated.
