Users Manual

3.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 Instrument.

4.Set the 5700A to output 0V dc

5.Using either a terminal or a computer running a terminal emulation program as the selected host, send the following commands to Hydra Series II:

FUNC 0,VDC,I100MV <CR> MON 1,0 <CR> MON_VAL? <CR>

The returned value for channel 0 should be 0 mV ±0.006 mV.

Set the 5700A to output 90 mV DC. Send the following command:MON_VAL? <CR>

The value returned should now be 90 mV ±0.028 mV (between 89.972 and 90.028 mV).

6.Change Hydra Series II's channel 0 function to the internal 1V dc range by redefining channel 0. Send the following commands:

MON 0 <CR>

FUNC 0,VDC,I1V <CR>

Set the 5700A to output 0.9V dc. Send the following commands: MON 1,0 <CR>

MON_VAL? <CR>

The value returned should be 900 mV ±0.21 mV (899.79 to 900.21 mV).

4-Terminal Resistance Test

Assure Channel 0's Accuracy Verification Test for DC Volts and Resistance meets minimum acceptable levels.

1.Switch OFF power to the instrument and disconnect all high voltage inputs.

2.Remove the Input Module from the rear of the instrument. Open the Input Module and connect a pair of test leads (keep as short as possible) to the H (high) and L (low) terminals of channel 1 and a second pair of test leads to the H and L terminals of channel 11. Install the Input Module back into the instrument.

3.Observing polarity connect channel 1's test leads to the Sense HI and LO terminals of the 5700A and channel 11's test leads to the Output HI and LO terminals of the 5700A. Connect as shown in Figure 6-2.

4.Switch the instrument ON.

5.Select the 4-terminal OHMS function, AUTO range, for channel 1 on the Hydra Series II Instrument.

6.Set the 5700A to output the resistance values listed in Table 6-3 (Use decades of 1.9).

7.On Hydra Series II press MON and ensure the display reads between the minimum and maximum values shown on Table 6-3.

8.The 4-terminal Resistance Test is complete. However if you desire to perform this test on Input Module channels (2 through 10) repeat steps 1 through 7 substituting in the appropriate channel number.
