For electricians, service technicians, and HVAC specialists who must test, debug, and fix a variety of electrical and electronic systems, multimeters are vital equipment. Using several measuring functions and test leads, a multimeter may measure a wide range of variables, including voltage, current, resistance, frequency, capacitance, and temperature.
Additionally, a multimeter is capable of transferring data wirelessly, detecting live wires, measuring current spikes, and analyzing waveforms.
But not every multimeter is made equal. When selecting a multimeter for your work, there are numerous things to take into account, including accuracy, dependability, functionality, design, and durability.
Additionally, keep in mind the manufacturer’s name and reputation. FLIR is among the most reputable and trusted manufacturers of electrical equipment. In addition to being a leader in thermal imaging and infrared technologies, FLIR also manufactures premium multimeters and other test equipment.
The DM90 and the DM93 are two FLIR multimeter devices that will be compared in this article. Both instruments are portable digital multimeters that can measure a range of parameters and share some characteristics.
Nevertheless, they also differ in a few ways that, depending on your needs and preferences, may influence your choice. We will highlight the differences and similarities between the two models in terms of usefulness, performance, durability, and design.
In order to bolster our arguments and give our piece more legitimacy, we will also incorporate some user feedback or testimonials from Amazon or other sources.
Handheld digital multimeters like the FLIR DM90 and FLIR DM93 can measure a variety of things, including voltage, current, resistance, frequency, capacitance, temperature, and more.
Additionally, they share some characteristics, such as:
In variable frequency drives, motors, and drive controllers, non-sinusoidal waveforms and noisy signals are analyzed in the VFD mode. The true voltage and frequency of the VFD output, which are susceptible to interference and harmonic distortion, can be precisely measured in this mode.
In long-run applications, LoZ mode can be used to get rid of ghost voltage measurements. This mode lowers the multimeter’s input impedance to less than 3 k, preventing misleading readings brought on by stray voltages created by surrounding wires or machinery.
Bright dual LED worklights to brighten settings with low lighting. On/off switches for each of these worklights are positioned on the multimeter’s rear. They cast enough light to plainly observe the measurement area and test leads.
Wireless data transfer and remote viewing are enabled using METERLiNK and Bluetooth connectivity. By using the FLIR Tools app, these features enable you to connect your multimeter to your smartphone or tablet and examine, analyze, and share your measurements in real time or at a later time.
To further your diagnostic and reporting capabilities, you may also link your multimeter to other FLIR products that accept METERLiNK, such as thermal cameras or clamp meters.
CAT IV 600V and CAT III 1000V rated design that is robust and shock resistant.
These ratings show how well-protected the multimeter is against electric shock and transient overvoltage. In industrial settings, CAT IV 600V indicates the multimeter can withstand up to 600 volts from the source to the ground, whereas CAT III 1000V means it can manage up to 1000 volts from the distribution panel to the outlet.
The multimeter also has a tough exterior that can withstand drops from three meters and water splashes (IP54 rating).
Nevertheless, there are some other distinctions between the two versions that may influence your decision depending on your requirements and tastes. Here are some of the key variations:
While the DM93 has a True Inrush measurement function, the DM90 has a True RMS AC voltage and current measurement function. When a multimeter has true RMS, it can measure AC voltage and current effectively on non-linear loads like computers, electronics, and lighting systems.
True Inrush refers to the multimeter’s ability to record the peak value of AC current bursts brought on by starting motors and other inductive loads. If not measured properly, these spikes might harm or trip circuit breakers, fuses, or relays.
While the DM93 has a potent worklight that can also be used as a flashlight, the DM90 has an integrated non-contact voltage detector that can detect live wires without touching them.
With the non-contact voltage detector, you can quickly determine whether a wire or an outlet is energized before testing it with the test leads, which is a convenient and safe feature. For working in dimly lit or cramped areas, the worklight/flashlight is a useful feature because it emits more light than the worklights on the multimeter’s back.
The DM93’s battery life is up to 400 hours, compared to the DM90’s up to 300 hours. Both multimeters are powered by four AA batteries, but the DM93’s reduced power consumption results in a longer battery life than the DM90’s.
Both multimeters have an automatic power-off feature that, in order to preserve battery life, turns the multimeter off after 15 minutes of inactivity. If desired, one can disable this feature.
The DM93 has a display resolution of 40,000 counts, compared to 6000 counts for the DM90.
How many digits or counts the multimeter can display on its screen is determined by the display resolution. Your measurements will be more accurate and detailed if they have a greater resolution.
A 6000-count display, for instance, can display up to 5999 counts (for instance, 5.999 V), whereas a 40,000-count display can display up to 39,999 counts (for instance, 39.999 V).
The DM93 features a data recording function that can record up to 20,000 readings with time stamps, compared to the DM90’s data logging function that can store up to 99 readings.
You can use either feature to save your measurements in the multimeter’s internal memory for later review or to transfer them wirelessly to a Bluetooth-enabled smartphone or tablet.
The data recording function, however, saves numerous readings per measurement function with time stamps, whereas the data logging function simply saves one reading for each measurement function.
You can see the recorded data on the multimeter screen in a graphical or tabular manner and configure the recording interval and length using the data recording function.
Additional information about each multimeter includes:
With a Type K temperature capability, the FLIR DM90 is a True RMS digital multimeter that can detect temperatures between -40°C and 400°C using a thermocouple probe.
The 6000-count display on the FLIR DM90 has a backlight and a bargraph that displays the measurement result and the signal’s relative strength.
The FLIR DM90 features two functions: a peak min/max function that records the minimum and maximum peak values of AC voltage or current, and a min/max/avg function that records the minimum, maximum, and average values of measurements.
A hold feature on the FLIR DM90 stops the display reading, and an auto hold function starts the display reading freezing when it stabilizes.
For offsetting errors or comparing measurements, the FLIR DM90 offers a relative function that shows the difference between the current reading and a reference value.
