True-rms Digital Multimeters Symbols XWWarning To avoid possible electric shock, fire, or personal injury, follow these guidelines: • Do not alter the Product and use only as specified, or the protection supplied by the Product can be compromised. • Do not use the Meter if it is damaged. Before you use the Meter, inspect the case.
287/289 Calibration Manual • When servicing the Meter, use only specified replacement parts. • When using probes, keep fingers behind the finger guards on the probes. • Do not use the Low Pass Filter option to verify the presence of hazardous voltages. Voltages greater than what is indicated may be present.

287/289 Calibration Manual AC Floor: When the input leads are shorted together in the ac functions, the Meter may display a residual reading up to 200 counts. A 200 count residual reading will cause only a 20 count change for readings at 2 % of range. Using REL to offset this reading may produce a much larger constant error in later measurements.

True-rms Digital Multimeters Basic Maintenance Basic Maintenance XW Warning To avoid electrical shock or personal injury, remove the test leads and any input signals before opening the case or replacing the battery or fuses. To prevent damage or injury, install ONLY batteries or fuses specified for this product. Opening the Meter Case W Caution To avoid unintended circuit shorting, always place the...
287/289 Calibration Manual Reassembling the Meter Case To reassemble the Meter case, do the following: 1. Verify the rotary switch knob is in the position (arrow on the rotary switch detent points straight up to the LCD). 2. Install the display bezel, LCD, and top shield into the top case. 3.
3. Remove either fuse by gently prying one end loose, then lifting the fuse out of the fuse contacts. 4. Install only Fluke specified replacement fuses with the amperage, voltage, and interrupt ratings shown in the replacement parts list (see Table 9).
To perform the tests you will need a Fluke 5520A Calibrator or equipment meeting the minimum specification given in Table 2. Prior to beginning the accuracy tests, allow for the Meter to stabilize to room temperature.
True-rms Digital Multimeters Performance Tests Factory Default Prior to completing the Performance tests Reset the Meter to the factory defaults as follows: 1. Power the Meter on in any function. 2. Press F4 (Setup) and select Reset using arrow keys. 3.
Append line feeds to incoming line ends Wrap lines that exceed terminal width 9. Enter the identification command <ID> followed by carriage return (Enter) 10. The Meter should return the response: FLUKE 289, VX.XX, X, indicating the model, software version, and serial number. Note...
True-rms Digital Multimeters Performance Tests 1. Turn the Meter on and position the rotary switch to and select the temperature function. Select the degrees C function key. 2. On the Meter, select Offset. Adjust the offset to 000.0 using keypad edit buttons. 3.

True-rms Digital Multimeters Calibration Adjustment Calibration Adjustment The Meter features closed-case calibration adjustment using known reference sources. The Meter measures the applied reference source, calculates correction factors and stores the correction factors in nonvolatile memory. The following sections present the features and Meter pushbutton functions that can be used during the Calibration Adjustment Procedure.

The F1 key [OK] is used to return to the measurement mode. Restoring Factory Default Password Restoring the factory default password [1234] can be done as follows: 1.
True-rms Digital Multimeters Calibration Adjustment Screenshot Description The following describes the Meter dialog shown in Figure 4 Screenshot. 1. Live Reading measurement shown in the Primary display is using default calibration constants. The measurement is likely to be slightly different from the applied signal, because it is an uncalibrated measurement.
287/289 Calibration Manual seconds). If the measurement is within calibration tolerance the Meter records the new constant(s) and proceeds to the next calibration step, giving a single beep to prompt the user to proceed. Note The frequency value for AC functions will not be validated. If the measurement is not within calibration tolerance then after pressing NEXT an error message will be shown and the calibration step will not proceed.
