First impressions of Fluke 177
Before we dive in and see what the multimeter packs within, let’s first see what you get out of the box. Besides the Fluke 177 multimeter, you’ll have a 9V battery that should take you a while.
For those who’ll be using a multimeter for the first time, there’s a user manual. I'd, however, recommend that everyone goes through this before using it to ensure you use it right. The multimeter also comes with a protective holster and a pair of test probes.
A look under the hood
In addition to coming with handy accessories right out of the box, here’s more you should look forward to with this multimeter.
True RMS for utmost accuracy
As you can tell from the name itself, this is a true RMS digital multimeter. Since this applies to both current and voltage, it should be accurate enough in measuring both sinusoidal and non-sinusoidal waves.
The True RMS feature will also be really handy for professional use such as measuring variable speed AC motors. It should be good enough to give you the accuracy you need on inverters irrespective of the distortion of the waveform.
Top of the line display
It’s not in vain that the Fluke 177 ESFP stands out as one of the best-looking meters in the market. As it turns out, the display is quite amazing. Being a 3 ¾ digit display with 6000 counts, it reads up to 59.99 before updating to 60.0.
It is also worth mentioning that the main display has got an additional digital bar graph. This is designed to update 40 times every second which is quite impressive. To add icing on the cake, the bar graph has got 33 segments which are ideal for keeping tracks of signals that change rather fast.
For the sake of convenience, it also comes with a backlit display. With this, the multimeter should be usable in low light conditions. What’s even more interesting is that when used with the backlit off, it should get you as much as 200 hours on a single 9V battery.
Something else that picked my interest is that below this amazing display are amazing labels for the dial. This way, it was easy for me to switch between the numerous measurement functions it has.
Includes a power-saving function
This is one feature that picked my interest on the Fluke 177 ESFP True RMS Digital Multimeter. The fact that the multimeter can automatically turn itself off after 2 minutes of inactivity was resourceful.
In addition to this, the auto power-off feature can be disabled with a power-up option. This way, anyone should pretty much be able to use this bad boy.
It boasts a convenient memory function.
Besides just having an optional auto power-off feature, you will also appreciate the memory function that comes along with this.
This includes the maximum, minimum and average functions which work by picking the max and min values then averaging them out. Alongside the memory function is also an auto-range which works in such a way that the meter selects the range that's got the best resolution for the measurement value selected. You can also switch to the manual range function at will when need be.
There is also a data hold feature that holds the reading once the hold button is pressed. The reading is maintained until a new stable input is detected at which point the meter beeps and displays the new reading.
Observes safety at its best
It's not a good enough multimeter if safety is overlooked, is it? Well, to ensure that you get to do all your troubleshooting correctly and the multimeter itself is not compromised, it has the CAT III and CAT IV ratings. The former is rated at 600V and the latter is rated at 1000V which means this will be safe for home and industrial use.
Besides the above-mentioned safety ratings, it also has integrated overfolded protection. This should serve as a good enough impact protection for the multimeter especially if you'll be using it outdoors.
Something else worth pointing out about the design of this bad boy is that it has got probe holders built into the multimeter. This makes the storage of probes easy and also makes the multimeter convenient enough to use when making measurements.
Comes with lots of measurement functions
To ensure it can be used in lots of different scenarios, it packs a lot of measurement functions in a compact unit. First, the AC and voltage are specified from 5% to 100% of range. Besides the voltage and current, it can also be used to measure capacitance, resistance, continuity and diode measurements.
Also, when the need for any calibrations arises, you can utilize the closed case calibration through the front panel.
We’ve seen what there is to look forward to in the Fluke 177 and it’s no time to round things up. From all the features it has, it’s clear that this is one of the best TRMS multimeters an electrician could get which also serves as an amazing household multimeter. From the display and functionality to the safety and build quality, you couldn’t go wrong with this bad boy.
