Operation
For highest accuracy:
• Lay the meter flat on a non-metallic surface, away from any magnetic objects.
• Read the scale straight on — not at an angle.
• If possible, select a range that results in a reading in the upper 1/3 of the scale.
1. Unlock the pointer.
2. Zero the meter as follows: With the test leads disconnected, adjust the Mechanical Zero
Screw to set the pointer to the far left side of the scale.
3. If taking a resistance or temperature measurement, adjust the meter as follows:
a. AM-600 and AM-600T: Before taking a resistance measurement, set the meter to the
appropriate resistance range. Connect the tips of the test leads together and read the
meter. Use the Ohm Adjustment Knob to set the pointer to the far right side of the scale
(zero ohms).
b. AM-600T only: Before taking a temperature measurement, set the meter to (TEMP).
Connect the test leads to the meter as shown under Typical Measurements. Use the
Ohm Adjustment Knob to set the pointer to the far right side of the scale (zero ohms).
Note: If you cannot adjust the pointer to the far right side of the scale, replace the battery.
If you cannot get a proper adjustment after replacing the battery, send the unit to Greenlee
for repair.
4. See the Settings Table. Set the selector to the proper setting and connect the test leads to
the meter. Start with the highest measurement setting.
5. See Typical Measurements for specific measurement instructions.
6. Test the unit on a known functioning circuit or component.
• If the unit does not function as expected on a known functioning circuit, replace the
battery and/or fuse.
• If the unit still does not function as expected, send the unit to Greenlee for repair. See
the address shown under Warranty.
7. Take the reading from the circuit or component to be tested. If the resolution is not
satisfactory, remove the meter from the circuit and change to the next lower range.
8. Lock the pointer when finished.
