True RMS Multimeters Testing the Fuses Testing the Fuses XWWarning To avoid electrical shock or personal injury: • Remove the test leads and any input signals before replacing the battery or fuses. • To avoid electrical shock, arc blast, or damage to the Meter, install only fuses with the amperage, interrupt, voltage, and speed ratings specified in Table 5. To test the fuses (refer to Figure 1): 1. Set the Rotary Switch to e. 2.
175, 177, & 179 Calibration Information Replacing the Fuses XWWarning To avoid electrical shock, arc blast, or damage to the Meter, install only fuses with the amperage, interrupt, voltage, and speed ratings specified in Table 5. To replace the Fuses (refer to Figure 2): 1. Turn the Rotary Switch to OFF. 2. Disconnect the test leads and/or any connectors from the terminals. 3. Remove the four screws from the Case Bottom and separate the Case Top from the Case Bottom. 4.
True RMS Multimeters Cleaning Cleaning XWWarning To avoid electrical shock: • Remove test leads and any input signals before cleaning. • Do not reinstall the pca until it is completely dry. Dirt or moisture in the terminals can affect readings. W Caution To avoid damaging the Meter, do not use aromatic hydrocarbons or chlorinated solvents for cleaning. These solutions will react with the plastics used in the instruments. Do not use detergents of any kind for cleaning the pca.

Removing the LCD Mask Performance Tests XWWarning To avoid electric shock, do not perform the performance test procedures unless the Meter is fully assembled. The following performance tests verify the complete operation of the Meter and check the accuracy of each Meter function against its specifications. If the Meter fails any part of the test, calibration adjustment and/or repair is indicated.
True RMS Multimeters Performance Tests Required Equipment A Fluke 5500A Multi-Product Calibrator (or equivalent) is required for the performance test procedures in this document. If an equivalent calibrator is used, it must meet the accuracy specifications shown in Table 1. Table 1. Calibrator Specifications Recommended Equipment 5500A Multi-Product Calibrator (or equivalent) Measurement Function Accuracy DC Volts 30 mV to 1000 V ±0.0225 % DC Current 3 mA to 9 A ±0.
175, 177, & 179 Calibration Information Performance Tests Note When calibrating or measuring AC current, avoid the potential for errors from coupled noise, by either: 1. Shorting the VeG to the COM input or 2. Having NO connection to the VeG input. 1. Set the UUT Rotary Switch to the position called for in Table 2 (175) or Table 3 (177/179), and for all measurements other than current (amps), connect the calibrator to the VeG and COM input terminals.
