5. Press T, and verify that the UUT reading is within the display reading limits
shown in Table 9.
6. Connect the Fluke 5320A high resistance output terminals to the UUT

2-Ohm Output Current Test
The following procedure verifies the minimum current for a 2-Ω Load in continuity
function:
1. Connect the Fluke 5320A low resistance output terminal to the UUT
terminals.
2. Set the Fluke 5320A to the low resistance source function (L) and 2-Ω output.
3. Set the UUT rotary function switch to the Ω function.
4. Press the UUT T. The Fluke 5320A current reading should be > 200 mA.
Open Circuit Voltage Test
The following test confirms that the open circuit voltage for the UUT Ω function is
within limits.
1. Connect the Fluke 5320A
terminals observing correct polarity.

2. Set the Fluke 5320A to the M mode and dc volts.
3. Set the UUT rotary function switch to the
4. Press T and verify that the Fluke 5320A voltage reading is > 4.0 V but
< 8.0 V.
