Accuracy Verification Test - Fluke Hydra Series II User Manual

Accuracy Verification Test

1. Power up the instrument and allow the temperature to stabilize for 30 minutes.
2. Connect a cable from the Output VA HI and LO connectors of the 5700A to the VΩ
and COM connectors on the front panel of the Hydra Series II. Select the channel 0
function and range on the Hydra Series II and the input level from the 5700A using
the values listed in Table 7-3. Press the M (monitor) button to measure and display
the measurement value for channel 0. The display should read between the minimum
and maximum values listed in the table.

Voltages greater than 150V can only be applied to channels 0, 1, and 11. The rear Input Module must
be installed when measuring ac volts on channel 0.
For 2-terminal measurements, the resistance accuracy given in this table applies to Channel 0 and
makes allowance for up to 0.05 ohm of lead wire resistance. You must add any additional lead wire
resistance present in your set up to the resistance values given in this table.
