Preparation
1. First select the test current that will be used for performing the Protective Earth
Resistance test by pressing AMPERES (SOFT KEY 3).
2. Connect the test lead(s) between the RED input jack and the GREEN input jack.
3. Press CAL LEADS. The 601PRO will measure the lead resistance, and if less than 0.150
Ohms, it will store the reading and subtract it from all earth resistance readings taken at
the calibrated current.
If the calibration fails, the previously stored readings will be used until a passing calibration
has occurred.
WARNING
z
During Earth Resistance testing, the DUT must be plugged into the 601PRO
front outlet. If the DUT fails Earth Resistance, discontinue tests and label the
device defective.
To Perform the Test
1. From the MAIN MENU, or with the outlet unpowered, plug the DUT into the 601PRO
front panel outlet.
2. Attach the 601PRO RED input lead to the device’s Protective Earth terminal or an
exposed metal area.
3. Press shortcut key 3. The Protective Earth Resistance test is displayed.
4. Press SOFT KEY 3 to select a test current (25 amp). The selected test current is
displayed in the upper right corner of the display.
5. Press START TEST to start the test. The test current is applied while resistance and
current readings are taken. This takes approximately 5 seconds.
6. Press the print data key at any time to generate a printout of the latest measurement(s).
