When making earth resistance measurement using a wall outlet, which is on the
secondary side of mains power supply, use a probe with a blade type prod,
instead of an alligator clip, as earth probe. (See section 8 "Adapters for Earth
Lead and Replacement") Locate earth of the outlet and insert the blade type
prod into it.

2. Check earth voltage.

Select the "earth voltage AC 60V " range and check whether the reading is 10V
or less. When earth voltage is more than 10V, it may result in errors in the
reading. To avoid this, reduce the earth voltage, for example, by disconnecting
mains from the equipment connected to the earth electrode under test.

3. Select the desired simplified earth resistance range and press the test button.

Multiply the reading by 10 on the x10 range or 100 on the x100 range.

4. Set the range selector switch to the OFF position.
