- Page 2 The sonde must emit a 512 Hz signal and the receiver can determine the approximate depth of the target. The CR512R is designed to be intuitive and require minimum of training for effective use of the instrument. The controls and the information display area are large and easy to understand. Yet they include everything necessary to control the receiver with your thumb.

- Page 4 Battery indicator – Shows the status of the battery health. Getting to Know your Tools Your CR512R receiver supports the detection of any standard 512 Hz sonde or camera in the market. This type of sonde or camera is usually attached to devices that are sent through non-metallic sewer-lines or water pipes.
- Page 5 Start by turning on the receiver and walking around and holding the receiver at waist height and walk towards general direction of the transmitter while slowly sweeping the receiver back and forth while pointing in the direction of the transmitter. You will notice that the signal will get louder and the meter will begin to move to the right.
- Page 6 Now let’s look at some other places to find nulls. Back away from the transmitter and walk past it off to the end like the image below: There was a null just as you crossed the axis of the transmitter, just like before this is called a “crossing null”.
- Page 7 Crossing null Crossing null What’s so special about this? Well, imagine that you can’t see the transmitter, which is just like a real-world situation. In fact, have someone put the transmitter under a box or newspaper and orient it in a way you can’t see. Using the circle method, you can quickly determine which way the transmitter is lying.
- Page 8 Find the “Peak Spot” Take the receiver in your hand and turn the sensitivity knob all the way up and flip the toggle switch to “Far”. Hold the receiver parallel to the ground at waist level. Walk around the area you expect the transmitter to be in, moving the receiver in an arc, back and forth.
- Page 9 directly below the center of the rod). You will find that they are directly across the circle from each other, and describe a line that passes right through the peak area. Crossing null Crossing null You have just identified the two “Crossing Nulls”, and the line between them indicates the lay of the line is parallel to the axis of the transmitter, and we will assume for the moment that line is running straight through that point, along the line of the Crossing Nulls.
