6.2 Single Point Grounding System, Auxiliary Measurement

For single point grounding systems where direct clamp measurement of the lead wire is not feasible, auxiliary methods can be used. The two-point method is illustrated below:

Image 6.2: Diagram showing the two-point method for auxiliary grounding resistance measurement. It depicts a grounding rod (RA) connected to a single point, with a wire extending to a natural grounding point (e.g., water pipe, buried metal) for measurement.

هن طريقي کي استعمال ڪرڻ لاء:

• Identify a natural grounding point with a low resistance value near the grounding point to be measured. Examples include a water pipe, fire hydrant, or other deeply buried metal structure.
• Connect a wire from the point to be measured to this auxiliary grounding point.
• Clamp the ETCR2100A+ around the connecting wire to perform the measurement.

6.3 Data Storage and Retrieval

The instrument can store up to 99 sets of measurement data.

• To store data: After a measurement, press the ايم ايم button to save the current reading.
• To retrieve data: Press the ايم ايم button repeatedly to cycle through stored data.

6.4 الارم فنڪشن

The ETCR2100A+ features an audible and visual alarm for out-of-range measurements.

• To activate/deactivate the alarm: Press the AL بٽڻ
• To set alarm thresholds: Refer to the device's on-screen menu or specific instructions for setting resistance (1-199 Ω) and current (1-499mA) alarm limits.
