Holster and Flex-Stand 18 Applications Measuring Voltage (AC/DC) To measure voltage, connect the meter in parallel with the load or circuit under test. Each of the five ac/dc voltage ranges presents an input impedance of approximately 10 M in parallel with less than 100 pF. To improve the accuracy of dc voltage measurements made in the presence of ac voltages, measure the ac voltage first. Note the ac voltage range and manually select a dc voltage range that is the same or higher than the ac voltage range. This method improves the dc voltage accuracy by ensuring that the input protection circuits are not being activated. A typical application is measuring the dc offset voltage of an amplifier in the presence of an ac signal. Measurement errors due to circuit loading can result when making either ac or dc voltage measurements on circuits with high source impedance. In most cases, the error is negligible (0. 1% or less) if the measurement circuit source impedance is 10 kilohms or less. Measuring Current Warning Do not attempt an in-circuit current measurement where the potential to earth is greater than 1000V.
