Low Resistance Meters e.g. Micro Ohm Meter, Milli Ohm Meter work with the principle of 4 wire measurement. Two terminals provide test current and two terminals a re used for sensing voltage drop. It is very difficult to buy Low Resistance standards at affordable prices.ZEAL make, 4 Wire Low Resistance Standard serves the purpose of accuracy and economy. The resistance values are very stable over years. Low resistors of values of 10µΩ,50µΩ, 100µΩ, 1mΩ, 10mΩ, 100mΩ, 1Ω have been fitted in an enclosure with provision for each resistor’s current terminals and drop terminals.

It is essential to carry out screening of diodes out of the strip particularly for reverse breakdown test at acceptable leakage current in µA. To take out diodes one by one and conduct tests will be a time consuming and fatigue prone process. The risk of DC high voltage for an operator is always there.Tester has motor driven geared mechanism to pull strip of diodes with test riders applying reverse voltage on the leads. Whenever leakage current exceeds than the acceptable limit, the motor comes to halt with audio/visual trip indication. Test voltage is removed. Operator has to take out the faulty diode and continue with the further testing.

ZEAL supplies highest performance resistance standards. With a very low-temperature coefficient, these highest stability sealed resistance to make an ideal standard for precision applications inside or outside of laboratory environment. Because of the low-temperature coefficient, they require no oil-or-temperature bath. It is possible to maintain ZEAL resistance standards indefinitely. They are reliable due to their closed, rugged design.

It simulates 2-wire transmitter to calibrate receivers, recorders, controllers, indicators. Loop power eliminates the need for batteries. Loop current is clamped at the key value you select. Accuracy is ±0.1% of 4 to 20 mA, even with changes in load and supply voltage. Switch settings of 0, 25, 50, 75 and 100% gives user fast, full range check out of UUC. The single rotary switch and light in weight case have been designed for simple, one-handed operation. Just insert the banana to crocodile cables in the banana sockets to the UUC. When you check out receivers, recorders or controllers in a 2-wire 4 to 20mA loop, simply disconnect the 2-wire transmitter and hook up a Model: ZMTCS. Flip a switch to get instant full scale and zero outputs. The calibrator operates just like a 2-wire transmitter by modulating the external power supply voltage into a 4 to 20mA signal.

The Ground Continuity Test is performed by measuring the resistance between the third pin (ground) and outside metal body of the product under test. The maximum acceptable value is generally 0.1 ohm. This test is generally carried out at a slightly higher current (e.g. 30A) so that the ground bond circuit maintains safe voltages on the chassis of the product, even at a high current, before the circuit breaker trips or fuse blows. This test is essential so that the product does not cause an electric shock resulting from insulation failure.
