- Page 3 Part I- Your HF35C Meter Features and User Instruction This meter is very user friendly and simple to operate with just three buttons and an audio volume dial, yet it offers lots of useful features for fast, reliable measurement of EMF from common radio/microwave sources.
- Page 4 You’ll find health safety standards (i.e. the exposure limits) for radio/microwave fields included at the end of this guide for reference as you use your HF35C meter. Naturally, health safety standard limits also exist for electric and magnetic exposure, body voltage etc., however for these you will need a different meter capable of detecting and measuring those types of fields.
- Page 5 Assembling Your Meter Find the shaped slot on the end of the meter, insert the green antennae securely into the opening. The copper wire from the antennae then screws snugly onto the antennae terminal on the right side (where you see the antennae symbol). It generally comes with a 9-volt battery that you will need to install.
- Page 6 The power button is the lower of the two buttons on the right side; slide it up vertically to switch on. Naturally, to conserve battery life, you will want to remember to turn the power off when you are not actually measuring with the meter.
- Page 7 This meter is a single axis directional meter, meaning it measures signals in one direction only, at one time. The word ‘signal’ is commonly used interchangeably with the word ‘field’ (meaning specifically an electromagnetic field). Since this meter is directional, signals coming from other directions are not included in the read-out display to the full extent that they actually exist around you.
- Page 8 Simplifying the individual words to their common English language meaning - power flux density is the measure of “energy change concentration” -- may also help clarify its meaning. The engineers and scientists among us though will understand power flux density as a term of measurement to express the amount of power impacting on a surface, which is used in a wide range of applications from chemistry to electronics to astronomy.
- Page 9 For EMF protection purposes, we are more concerned with the Peak setting since it will tell us the full magnitude of exposure, the maximum power flux density detected, which is what studies most correlate with harmful biological effects, at least up until recently since they’ve began correlating them with field strength.

- Page 11 Secondly, it is economical for a meter of this quality. The 32D model, although less expensive does not measure down to .1 and it does not offer the audio or the Peak Value feature. The 38B model has a bit more frequency range on the end but it is both much more expensive and more delicate for new users.

- Page 18 The HF35C and HF38B feature additional settings as described below: At first, set ”Range“ to ”1999 µW/m²“ resp. ”19.99 µW/m²“ (HF38B). Only if there are constantly very small readings, switch to the next finer range. The basic rule for any type of metering is to use the scale that is “as coarse as necessary, as fine as possible”.

- Page 24 PART III - Your Radio/microwave Meter at Work in Real World Situations EASY INTRO TO GETTING STARTED with Your HF35C Meter: Measuring Radio/Microwave Radiation Once you have assembled your meter and its antenna (carefully), you’re ready to go. Hold the HF35C meter with a slightly outstretched arm, your hand at the rear of the instrument.
- Page 25 Shift & Sweep the instrument in order to find the point of maximum exposure. Simply shifting or moving the meter (using a slow sweeping motion in front of you) will enable you to find the true maximum signal strength in that area. Since signals in traveling through the air can sometimes cancel themselves out (just like opposing waves in a pond cancel each other out resulting in the sum of the two being less than either one), by sweeping the area you can avoid being impacted by local cancellation...
- Page 26 Certain areas read particularly high on your meter display if you are measuring at close range. Some are too high at close range for the meter to measure. These include microwave ovens, and cellphones, DECT mobile phones, and a multitude of wireless devices, but also may include things like airport radar sweeps, and FM tower transmissions.
- Page 27 Since today’s EMF safety standards (including radio/microwaves) are not biologically based it is up to the individual to become aware of their own exposure levels and take precautionary action. One of the first lines of defense is measuring the fields, so as to be able to assess the exposure levels and respond appropriately, which is to act ‘defensively’, and one of the most effective ways is simply to keep our distance.
- Page 28 Putting Your Meter to Work: Detecting and Protecting In this situation we want to measure for sources of radio/microwaves beyond the wooden privacy fence that borders this residence’s backyard, to determine if the small children who play here are exposed to unacceptably high exposure levels from next door. The main goal of using our meter is to locate the strongest signal.
- Page 29 So, the third motion we perform with the meter is shifting our meter systematically up and down, right and left, while very slowly ‘sweeping the air’ (as though sweeping ahead of ourselves with the beam of a flashlight) to find the strongest signal. By using these various motions we can locate the greatest signal strength and assess the full extent of the radio/microwave impact on this patio play yard where the children and the family spend a great deal of time.
- Page 30 Defending Your Home and Your Health It is not unusual in today’s world to discover, with the help of your HF35C meter, that the strongest EMF fields that you are ever exposed to are right inside your own home. The good news is that this is where we have the most control and the most ability to defend ourselves from unwanted radio/microwave exposure.

- Page 32 What Can I Do To Reduce RADIO/MICROWAVE Fields? Now that you are investigating your environment with your HF35C you’re beginning to notice that some sources elicit very high measurement readings from your meter. If these are located in areas where you spend lots of time you should first consider using distance as an easy means of lowering your exposure levels from these sources.
- Page 33 Your HF35C Meter at Work in the World: Various Ways it will Serve You Seeking EMF Refuge in Remote Locations This meter is a big help when you are searching for an EMF- pristine environment to spend some restorative, recreational time in.
- Page 34 Distinguishing Various Types of Meters The meter’s directional properties enable you to distinguish continually broadcasting smart meters, from continually broadcasting power line communication (PLC) meters, and on-demand radio-interrogated meters, from analog meters. By identifying the meter (from among the many others that are probably simultaneously broadcasting signals in the neighborhood vicinity) and listening/measuring the rate and power of signals you can identify what type of meter you are dealing with.
- Page 35 Performing Before and After Reading to Determine the Effectiveness of Remediation Measures This radio/microwave shielding fabric was installed to cover a wall of windows, in order to remediate the high measurements of radar coming straight into the home from the direction of the local airport. The directional feature of this meter came in handy in another completely unexpected way.
- Page 36 PART IV – Some Things You Might Find Interesting About This Meter Visualizing How Your Meter Sees Your HF35C meter measures in one direction and it picks up signals in an area the size of one square meter. Here is an illustration to help you visualize its measuring area. You’ll discover that this is a very useful meter to use to measure radio/microwave fields that are being caused by sources on the other side of walls, or otherwise out of sight.
- Page 37 Why Your Meter’s Antenna Looks the Way it Does Interestingly, this meter’s antenna actually illustrates the correlation between the design of the probe and the signals that are being measured in the environment. It detects the higher frequencies at the narrow end of its antenna and lower frequencies at the wider end.
- Page 38 For example, many of these toy-like meters simply display colored lights – red for stop, green for go type of display -- without letting you know what exactly it is measuring, or what it is basing its red/green determination on. Ghost buster radio/microwave “toy meters”, and EMF-alert type meters, fall into this category.
- Page 39 Add to this, not all types of audio meter manufacturers use the same sound ‘conventions’ when designing their instruments. So, take this video to simply be an example of various “typical” sounds, as a clue to help you in your detective work ferreting out sources. These types of meters are designed to measure field strength, not really to identify sources by sounds.
- Page 40 Taking into Consideration the Inherent Limitations of your HF35C Meter The deployment of 5G cellphones will be a game changer for radio/microwave detection meters, because at this writing we do not know what radio frequencies will officially be government approved for its use, or what EMF detection meters will have the ability to read those frequencies.
- Page 41 The different transmission properties of higher frequencies will necessitate a greater number of short range base stations that also are more densely located, installed throughout our environment. 5G base stations typically look similar to cans of soda-pop installed on lamp- posts, and broadcast less than 300 yards/meters.
- Page 42 Part of the Confusion is the Vast Difference Between Standards Notice that when you are reading RADIO/MICROWAVE measurements and comparing them to the various standards you want to follow, you will need to double check to make sure the units it is expressed in. Sometimes the units of the allowable safety standard and the biological standard are so vastly different that we need to change the units of scale so that we do not use an entire page of paper including the zeros.
