Fluke 115 Multimeter External Features

It has to be solid feeling quality in hand; plastic is an adorable selector switch. It does have a close solid yellow colour external boot housing. It is a True RMS. It has a hold button, a min-max, average to double-check manual range switch yellow button for the second functions for some of the selections. And it does have a backlight. And it does have an excellent standing bail.

At the bottom, you have three inputs; one is common, Voltage, continuity, resistance, diode, and current. But one thing is negative which is missing; milliamps and microamps.

The display is a lovely addition, the size digit with nice solid glass on it. Backlight is certainly brighter in a darker place. The leads are reasonable, no complaints about the rubbery quality, friendly feelings in the hand, impressed by Fluke leads, 1000 CAT volt. Lovely to hold in hand nice pointed in the end. The probe ends are also of good quality. Jack ports are also of perfect quality.

Fluke 115 Multimeter Functions

Voltage Test

 Let’s turn the dial more and select the voltage. Smooth presentation of the bar graph, and it can read up to 6000 counts. So our voltage is 29.71 volts. We will press the manual range and let us see what will be the reading! So no complaint with the overshoot; we have got the same readings on the multimeter screen that is  29.71 volts.

Accuracy Test

Next, we are checking the accuracy. I have connected the multimeter to the Pin tray ( in this pin tray, we have all calculated voltages readings to check the accuracy of our multimeter). Our selector dial must be defaulted to on D/C volts; when we press the yellow button, it will show AC millivolts press again to default it to D/C millivolts. Our reading is 250.1 volts. In the pin tray, it is already mentioned 250.0, which means the multimeter is accurate.

We are checking it and the results of Fluke 115 are specs for A/C volts; the specified reading is 4.999, still well-specified. Reading spec for A/C volts is 1%. So it can afford the reading flicker up to 1%, which is highly acceptable.

Frequency Test

Frequency is our next check. Our selector is on A/C volts; Again, we push the yellow button to check frequency in hertz. Given hertz is 9.995 hertz and our Fluke 115 reading is 9.999hertz. We have checked different frequencies, and I am very impressed with very perfect, quick resolution while taking inconsistent readings.

D/C current test

Next, we are going to measure D/C current milliamp. We have 0.001 milliamps here. Our selection dial we will move to Amps. And the display screen is showing 0.001 milliamps, no further resolution on. So the ability to measure on milliamps should be on a current selector.

A/C current Test

Just go to the A/C side, move the selector dial to the A/C. 0.1 amps are our A/C amps.

We are about to check the resistance here, move the dial selector to Ohms,  now we will touch both the pointed ends of the leads. There is a reading of 0.1 Ohms resistance of the leads.

Diode Test

Next, we will do a diode test; the specification we have here can check up to 2 volts. We will take a simple diode. We recall a shock diode. The reading we observed is 0.148, which is very low.

Next, we will check a red LED., and I will show a drop across the 1.765, green LED again 1.781, and the blue LED that is unable to record display screen shows OL’. So now we will take another multimeter and check the blue LED.

Capacitance Test

Next, we are going to check the capacitance measurements in different ranges. First, a 2.2 nano farad capacitor let us check the meter reading on the screen. The screen is a flickering resolution between 2 and 3, which is fair enough to measure—an electrolytic of  1 microfarad that comes up on the screen 990 Nanos. Next, I have the 15 microfarad capacitor. Multimeter displays 15.4 mF. We have another electrolytic of 1000 microfarads, of which we measure 996 mF. Here we have one more prominent fellow, capacitance 4600 mF, and here we have a reading of 4603 on Fluke 115 screen.

Continuity Test

Now we move our dial to continuity, we will touch both the leads, and we can hear a continuous buzzer. So it certainly a latched continuity buzzer works very well and quickly.

Minimum-maximum-Average Check

Now I click on the minimum-maximum button. The first reading is max, you hear beeps, and it is recording down, and if I push the min-max button again, we have a minimum reading. And press the min-max button again. It will give you an average reading with time which is a handy feature of the multimeter. If you click it again, you can see your live reading, which you previously worked on.

THING I LIKE ABOUT IT

Portable polyester protective case

Compact and lightweight

Larger display

Reliable and accurate

THINGS I DIDN’T LIKE

No microamps

little bit Expensive

Frequently Asked Questions

Conclusion

Fluke 115 digital multimeter does have the excellent build quality, body protection and safety. Everything is perfect to me. However, the clarity of the digits are not very good like other flukes, and as we discussed, this fluke does not have milliamps and microamps. So overall, it is a reasonable multimeter except for some negative downsides, user friendly, easy to use and accurate.
