PERFORMANCE VERIFICATIONS

Perform the following analysis; if the meter conforms to the limits listed in Table 1 through 5 the meter is
functioning correctly. If the meter does not conform to any of the listed limits the calibration procedure
must be performed.

Performance Verification Preparation

1. Turn on th e calibrator, allow calibrator to warm up. Temperature stabilization
should be reached after 30 minutes.

2. Remove battery cover and using a calibrated meter to ensure the batteries measures a minimum of

2.4VDC. If the batteries measures under 2.4V DC, replace the batteries (see Battery Replacement on page

9) before beginning the performance test.

3. Input the values listed in Table 1 through 5.

CALIBRATION

Calibration Preparation

1. Turn on the calibrator, allow calibrator to warm up. Perform calibration at
23±2°C (73.4°F ±3.5°F) at relative humidity of < 70%. Temperature stabilization should be
reached after 30 minutes.

2. Disco nnect the test leads and turn the range switch to “OFF”.

3. Remove the two screws holding the case bottom.

4. Remove the case bottom using care not to damage the battery connector.

5. Using a calibrated meter ensure the batteries measures a minimum of 2.4V DC.
If the batteries measures under 2.4V DC, replace the batteries (see Battery Replacement on page 9).

Calibration Procedure

It is recommended that all IDEAL meters undergo the following calibration procedure on
an annual basis.

The class of calibrator or equipment should have an accuracy that exceeds, by an expectable ratio the
accuracy of this instrument.
