While single-sided power meters are typically cheaper, they also assume your power balance (the percentage of total power each leg is producing) is perfectly even at all times. Our experience using dual-sided power meters (which measure power output from each leg independently) shows this isn’t the case, though.
The professional team’s testing took into account ease of installation, how each EKG caliper performed, and whether it’s likely to stand up to long-term use.
How to Read an ECG Strip
ECG paper is a grid with a horizontal axis for measuring time.
- Each small square measures 1 mm and represents 0.04 seconds.
Each larger square measures 5 mm and represents 0.2 seconds.
The vertical axis is used to measure voltage. - In terms of voltage, 10 mm equals 1 mV.
The diagram below shows how to set up ECG graph paper and where to measure the different components of the ECG waveform.
The following formula can be used to calculate heart rate from an ECG strip:
- The heart rate is 300 divided by the number of large squares between the QRS complexes when the rhythm is regular.
- The heart rate is 75 (300/4=75) if there are four huge squares between typical QRS complexes.
With an irregular rhythm, the second approach can be used to estimate the rate. Multiply the number of R waves in a 6-second strip by 10. - The heart rate is 70 (7×10=70) if there are seven R waves in a six-second strip.
What to Consider Before Choosing the Best EKG calipers
Whether you are a pro or a DIYer, it is wise to consider the style, features, accessories and leads when choosing ekg calipers. There are many options out there. Consider these features before purchasing one of these tools to help speed up the process.
Basic and Advanced Functions
If you want the greatest versatility from your EKG calipers, make sure it can test both types of current: alternating current (AC) — electricity flowing through outlets in your home — and direct current (DC), the electricity stored in batteries. Moreover, a ekg calipers must perform at least two of the following three electrical tests in order to qualify as a ekg calipers:
- Current: How fast electricity circulates
- Voltage: The difference between the electric current flowing between two points
- Resistance: The amount by which the material carrying the energy resists electrical flow, such as wires
In addition to testing voltage, resistance, and current, advanced digital ekg calipers can often perform the following tests:
- Capacitance: Storage
- Temperature: The degree of heat generated within the circuit (frequently in both Fahrenheit and Celsius).
- Frequency: Electrical occurrence rate (measured in hertz)
Analog Versus Dial Display
EKG calipers with analog dials that have needles (like an old-time speedometer on a car). In bright sunlight, it can be challenging to read a digital readout, especially when numbers are hard to read. The number of analog meters has dropped, but they are still inexpensive, ranging from $10 to $70, and they can perform the three basic circuit tests; they cannot perform more advanced tests.
In today’s market, most ekg calipers are electronic, and they’re more expensive, ranging from $20 to $500, or even more, depending on quality and precision. In addition, some digital ekg calipers feature backlit screens to make them easier to see in bright light; others have auto-shutoff features that turn them off after a few minutes of inactivity.
Auto-Range Function
With a manual range of ekg calipers, it can be difficult to determine the approximate range of electrical current you’re testing. Having set the ekg calipers to a specific ohms range, you need to keep clicking until the ekg calipers provide a reading. ekg calipers with an auto-range function (available on digital models only) will save you time since you only need to choose the type of test to perform (voltage, resistance, and current). A readout will appear immediately after the meter matches the right range to the circuit by scanning through all the range options.
