To be clear, you're simply exceeding the range of the higher resolution mV scale provided by the meters.
In the case of the UT61E, that limit is stated to be 220mV, resolution 0.01 mV, in the manual (findable online if you've lost yours). On the V setting, when the reading is under 2.2V resolution is 0.V (0.1 mV).
The answer is don't use the mV scale for this case. Read the V scale. Convert to mV if you want.
0.V = 603.8 mV
I didn't look up the numbers for your fluke, but it's presumably a range issue there as well.

When you need a multimeter for testing electrical equipment around the home, it's vital to know what all those symbols around the dial mean.
Back in the early days of electricity, lab workers could measure electric current in a circuit using an ammeter (galvanometer) and voltage using a voltmeter. From there, they could calculate resistance.
In , British postal engineer Donald Macadie invented the AVOmeter, which measured all three quantities (A = amps, V = volts, O = ohms). Soon after, electricians working in the field got their hands on somewhat portable versions of this invention.
Today's multimeters do the same jobs as the AVOmeter, but they're more sophisticated and can do multiple other tests as well. Depending on the model, a multimeter can tell you whether a diode or capacitor is working, distinguish between alternating and direct current and measure wire temperature. Functions are denoted by symbols arranged around a dial.
Homeowners doing DIY electrical work don't need the same functionality as electronics technicians, so multimeters sold in hardware stores are less complicated than those at electronics supply outlets. Even so, the symbols can be difficult to decipher. Here's a rundown of the electrical terms and symbols you'll find on a basic multimeter for home use and what they mean.
Multimeter Symbols You Need to Know VoltageFamily Handyman
Multimeters can measure direct current (DC) voltage and alternating current (AC) voltage, so they need to display more than one voltage symbol. On some older models, the designation for AC voltage is VAC. These days, it's more common for manufacturers to place a wavy line over the V to signify AC voltage.
To signify DC voltage, the convention is to place a dotted line with a solid line above it over the V. To get voltage readings in millivolts (one-thousandth of a volt), set the dial to mV.

Like voltage, current can be AC or DC. Because the unit for current is ampères, or amps, the symbol for it is A.

A multimeter measures resistance by sending a small electric current through the circuit. The symbol for the unit of resistance, the ohm, is the Greek letter omega (Ω). Meters don't distinguish between AC and DC resistance, so there are no lines above this symbol.
On meters with range selection options, you can select the kilohm (1,000 ohms) scale and the mega ohm (one million ohms) scale, which are kΩ and MΩ, respectively.

Use a multimeter to test for a break in an electrical circuit. The meter measures resistance, and there are only two outcomes. Either the circuit is broken (open), in which case the meter reads infinite resistance, or the circuit is intact (closed), in which case the meter reads 0 (or close to it).
Because there are only two possibilities, some meters beep when they detect continuity. This function is denoted on the dial settings by a series of left-facing brackets of increasing size, like a sideways version of the wireless reception symbol on a laptop.
Diode and Capacitance TestsFamily Handyman
Electronics technicians are more likely to use the diode and capacitance tests than electricians or homeowners. But if you have a meter with these functions, it helps to know what the symbols mean.
The diode test function looks like an arrow pointing toward the center of a plus sign. When this function is selected, the meter will tell you whether a diode (a common electronics component that changes AC current into DC current) is working or not.
The capacitance function resembles a right-facing bracket to the right of a vertical line. Both are crossed by a horizontal line. Capacitors are electronic devices that store charge, and the meter can measure the charge.
The temperature function measures the temperature of the circuit wires. It's denoted by a thermometer.
Jacks and ButtonsFamily Handyman
Two leads are supplied with every multimeter, one black and one red. Some meters have three jacks and some four. The jacks into which you plug the leads depend on what you're testing.
At the top of the meter display, above the dial, you usually find two buttons, one to the left and one to the right.
An older analog multimeter with a needle needs to have more than one range setting. If the meter had only a large range, it couldn't be used for sensitive measurements because the needle would hardly deflect. On the other hand, if the meter had only a small range, any measurement exceeding that range, no matter what it was, would deflect the needle to its maximum.
Digital multimeters with LED displays were introduced in the s, and today most multimeters are digital. Some still have range settings that you select with a dial. But increasingly, the meter selects the range automatically.
Because these multimeters don't have range settings (which can occupy up to 18 dial positions), auto-range multimeters can have more functionality than those with manual range settings.
Note: Retain the owner's manual of your multimeter for reference. Keep the manual and the multimeter clean and dry in a quart- or gallon-size plastic zip-top freezer storage bag.
