Fluke 1587 insulation multimeter: Measurements

Fluke 1587 insulation multimeter is used for measuring Ac & Dc voltage, current, resistance, frequency and capacitances etc. From this article, it became easier for people who want to know steps for measuring different electrical quantities so that they can easily compare the techniques and conditions used for measurement. If you want to gather some basic introduction of this multimeter you may follow our previous article Fluke 1587 multimeter features.

How to measure AC & DC voltage with Fluke 1587 insulation multimeter?

Steps for measuring AC & DC voltage are:

1. Point the dial to ṽ for ac voltage & mV for millidc voltage.
2. Inside the COM jack insert the black lead.
3. Inside the jack insert the Red lead.
4. Connect firstly the black lead to the circuit and after that the Red lead.
5. If you want to measure the lowest and highest value then press Min/Max button.
6. For selecting particular range press the RANGE button.
7. If you want to write down the stable measurement then press the HOLD button.
8. Note the measurement display on the screen. When you have noted the readings, first remove the red lead from the circuit and then remove the black lead to avoid any electrical shock or damage to the device.

How to measure Resistance with Fluke 1587 insulation multimeter?

Steps for measuring Resistances are:

1. Turn the dial to Ω function.
2. Inside the COM jack insert the black lead.
3. Inside the jack insert the Red lead.
4. Connect firstly the black lead to the circuit and after that the Red lead.
5. For measurement, the meter sends small current through the circuit.
6. The resistance measured is the total resistance of all paths because the current flows through all possible paths between the probes.
7. Note the measurement display on the screen. When you have noted the readings, first remove the red lead from the circuit and then remove the black lead to avoid any electrical shock or damage to the device.

How to measure capacitance with Fluke 1587 insulation multimeter?

Steps for measuring capacitance are:

1. Firstly ensures that all the power to the circuit is cut off. If the capacitor is connected in ac circuit then set the multimeter to ac voltage or vice versa.
2. Point the dial to the capacitance function.
3. Inside the COM jack insert the black lead.
4. Inside the jack insert the Red lead.
5. Connect firstly the black lead to the circuit and after that the Red lead.
6. Connect the test lead to the capacitor terminals.
7. Press  this button to measure capacitor.
8. Note down the measurement displayed on the screen. When you have noted the readings, first remove the red lead from the circuit and then remove the black lead to avoid any electrical shock or damage to the device.
9. For accurate measurement remove the capacitor from the circuit.
10. Always ensures or check capacitor is not leaking or damaged from anywhere.

How to measure AC & DC current with Fluke 1587 insulation multimeter?

Steps for measuring AC & DC current are:

1. Point the dial to mA function.
2. Inside the COM jack insert the black lead.
3. Inside the mA, jack insert the Red lead.
4. Connect firstly the black lead to the circuit and after that the Red lead.
5. For Dc current measurement press  this button.
6. Break the circuit path to be tested. Touch the black probe to the more negative side of the break and touch the red lead to the more positive side of the break.
7. Turn on the power to the circuit.
8. Note down the measurement displayed on the screen. When you have noted the readings, first remove the red lead from the circuit and then remove the black lead to avoid any electrical shock or damage to the device.

How to measure Temperature with Fluke 1587 insulation multimeter?

Steps for measuring temperature are:

1. Point the dial to .
2. Inside the COM jack and jack insert 2 pin plug.
3. Meter measures the temperature of the Type K thermocouple.
4. Press  this button to measure temperature.
5. Press range labelled button to measure temperature in Fahrenheit & Celsius.

How to test continuity with Fluke 1587 insulation multimeter?

Steps for testing continuity are:

1. Point the dial to .
2. Inside the COM jack insert the black lead.
3. Inside the jack insert the Red lead.
4. Connect firstly the black lead to the circuit and after that the Red lead.
5. When meter measures the resistance less than 25 Ω, the meter will sound the beeper.
6. Uses an audible signal to indicate the shorts.
7. The meter detects the intermittent open and short lasting as little as 250 µs.
8. Press  this button for diode test.

How to test insulation with Fluke 1587 insulation multimeter?

Steps for testing insulation are:

1. Insert the test probes inside the +ve and –ve insulation terminals.
2. Point the dial to INSULATION position. When the dial is turned to this position check the battery load because if the battery fails the test and bot appear on the lower display then insulation test cannot be performed until the batteries are replaced.
3. To select the voltage press range labelled button.
4. Connect the probes to the circuit to be measured. The meter automatically detects if the circuit is energized.
5. To start the test, push and hold insulation test labelled button.
6. Keep the probes on the test points and release the insulation test labelled button.
7. Until a new test is started, the resistance appears on the primary display.
