Normalization of the Meter
The temperature inside the testing area needs to be 75°F
±3°F at 40% to 60% relative humidity. The meter needs
to stay at a temperature of 75°F ±3°F for approximately 2
hours for proper readings. The meter cannot be normalized
inside objects, enclosed boxes, containers or cases. The
temperature inside an enclosed case will differ from the
outside temperature. These cases will act as insulators to
the meter. The meter must remain stationary in the testing
area for about 2 hours without any significant changes to the
temperature.
NOTE: Accuracy is measured after normalizing the meter for
a minimum of 2 hours.
Calibration Test Procedure
• Use only the test leads that were supplied with the
meter.
• Clean around the banana jack and stereo jack located at
the top of the meter with 99% isopropyl alcohol. Oil from
human fingers can affect the accuracy of the meter.
• Set the Test Voltage Button to 10V HOLD. Press and
hold the Test Button. The measured voltage between
the two test leads should be 10V ±5%.
• Set the Test Voltage Button to AUTO. Press and hold
the Test Button. The measured voltage between the two
test leads should be 100V ±5%.
• Ensure that the Test Voltage Button is set to AUTO
when performing the following measurements. Always
