The Digital Ground Resistance Tester Model 4500 is designed for measuring very low resistance on large grounding systems, such as ground grids and ground mats.

It rejects high levels of interference voltages at DC or 60Hz and its harmonics, and can be used under difficult conditions such as high stray currents or excessive auxiliary electrode
resistance without substantially affecting accuracy.

The Model 4500 has three selectable test current ranges (2, 10, 50mA) and five selectable resistance testing ranges (2?, 20?, 200?, 2000? and 20k?). It is capable of direct readings with a resolution as low as 1m?.

With such a wide resistance capability, the Model 4500 is capable of measuring the resistivities of soil and other materials from below 10m?-cm to over 1M?-cm.

Readings are displayed on a large(0.71"), 31/2 digit LCD. The LCD blinks and a pointer on the display lights to warn of excess stray current or auxiliary electrode resistance, or when there is a lack of continuity between leads and electrodes. A beeper will notify the
user if voltage greater than 20 volts peak is present between terminals X (C1) and Y (P2) or X and Z (C2) when the ground leads are connected.

The instrument is fuse protected up to 500AAC to protect the instrument against voltage into the test leads.

Power is supplied by a rechargeable 12V battery; the tester may also be operated from an external 12VDC supply. A battery charge indicator and low battery indicator appear on the LCD and a dual-voltage charging unit is built into the instrument.

The heavy-duty, safety yellow case is dust and water resistant to ensure reliable field use. The cover may be detached while the meter is in use, if desired. Optional test kits are
available for ground resistance and soil resistivity tests.
