GPS-4660A/4660B
Digital Micro-ohmmeter
DC Current Resistance Tester 10A/20A
This very low resistance ohmmeter is a portable, microprocessor-controlled instrument used to accurately measure resistances of switches and circuit breaker contacts, transformer and motor windings, wire and cable samples, joints in busbars and more.
Resistance readings are shown in the alphanumeric display with up to a 5 digit-resolution. It allows to measure resistances of up to 50 kΩ, with a resolution down to 0,1 µΩ.
Measurements accuracy is guaranteed by the state-of-the-art system for signal-amplification, offset-free and with long-term stability. The equipment has a USB interface that allows to download the measured values to a computer for their later analysis.
Operation is very simple: Just connect the leads, switch-on the equipment, select the test current and press the start button. After a few seconds, direct reading appears on the display with the measure unit indication (Ω, mΩ or µΩ). If necessary, the display will show messages to help the operator (Low battery, Over-range, etc).
The equipment is housed in a rugged plastic case with a hinged lid and carrying handle. It is a
portable, strong, impact resistant and lightweight equipment, suitable to be used in outdoors
and under severe weather conditions. It supplies very reliable and accurate measurements both in laboratory and out in the field.
- The tester is controlled by a high-speed single-chip microcomputer, with fast response speed, stable measurement and easy operation.
- With two measurement modes-automatic measurement mode: the test current can be automatically selected according to the load; Manual measurement mode: There are 7 gears test currents can be chosen from 20A, 10A, 1A, 100mA, 10mA, 2mA and 1mA.
- Equipped with a 480×854 true color LCD touch screen, which is clearly visible under strong light, and can be used for both touch screen and panel buttons. Large capacity rechargeable lithium battery and waterproof case are suitable for outdoor use. (GPS-4660A integrates a mono LCD display)
- With a Bluetooth communication function, can do test operations or view the test result on the mobile phone after install the APP.
- The tester has USB interface and monitoring software, which can communicate with the computer.
- The protection function is perfect and can reliably protect the impact of the back EMF on the instrument, making the performance more reliable.
- The discharging function can automatically discharge after the test, and the discharge indication is clear to avoid any mis-operation.
- Converting resistance function, which can compensate and convert the temperature material of the test product.
- Alarm function, the resistance alarm value can be set.
- Automatic shutdown function, the tester will automatic shutdown after 15 minutes without any operation.
