Page 21: Measurement Principle
VII. Measurement Principle 1. Principle of Resistance Measurement The basic principle of ETCR in the measurement of resistance is to measure the loop resistance, as shown in the figure below. The jaw part of the Meter is comprised of voltage coil and current coil. The voltage coil provides excitation signal, and will induce a potential E on the measured loop. -
Page 22: Measurement Method Of Earth Resistance
VIII. Measurement Method of Earth Resistance 1. Multi-Point Grounding System As for the multi-point grounding system (such as electricity transmission tower grounding system, grounding cable communications systems, certain buildings, etc.), They usually pass the overhead ground wire (cable shielding layer) connected to form a grounding system. -
Page 23: Limited Point Grounding System
measured should be R1. Times of comparing tests in different environments and different occasions with the traditional method proved that the above assumption is entirely reasonable. 2. Limited Point Grounding System This is also quite common. For example, in some towers, five towers are linked with each other through overhead ground wire;... -
Page 24: Single-Point Grounding System
And the program would output the same number of grounding resistance values. 3. Single-Point Grounding System From the measuring principle, ETCR series Meter can only -21-... - Page 25 measure the loop resistance, and the single-point grounding is not measured. However, users will be able to use a testing line very near to the earth electrode of the grounding system to artificially create a loop for testing. The following presented is two kinds of methods for the single-point grounding measurement by use of the Meter.
- Page 26 So, if the measurement value of the Meter is smaller than the allowable value of the grounding resistance, then the two grounding bodies are qualified for grounding resistance. (2) Three-Point Method As shown in the figure below, in the vicinity of the measured grounding body R find two independent grounding bodies of better grounding state R...

Page 27: Bill Of Loading
In the above three steps, the reading measured in each step is the value of the two series grounding resistance. In this way, we can easily calculate the value of each grounding resistance: From: R1=RA+RB R2=RB+RC R3=RC+RA We get: RA=（R1+R3-R2）÷2 This is the grounding resistance value of the grounding body R To facilitate the memory of the above formula, these three grounding bodies scan be viewed as a triangle;... -

Unit does not switch on,batteries are good.
If the ETCR2000+ unit does not switch on despite having good batteries, possible issues include:
- Incorrect battery polarity: Ensure batteries are installed correctly.
- Poor contact of battery contacts: Check and clean or replace the battery contacts.
- Wrong battery type: Use the correct battery type.
- A break in the battery harness: Perform a continuity test; replace the harness if no continuity.
- Displaced POWER button: Re-assemble the button.
- Poor contact of power plug: Re-plug or replace the plug.
- Defective PCB or circuit component: Replace the PCB if current consumption is about 100mA or more at 6V.
