Loop testing without tripping out any type of RCD. The unique 5 mA test current means the unit will not overheat. The 8978 is the fastest non trip loop tester on the market The resistance of the individual conductors can be measured with a single press of the test button, enabling R1 & R2 values to beestablished on live circuits.
CAT IV 300V applications. High current loop tester. Single and 3 phase testing. 16 Hz to 400 Hz operation. Two wire lead set or mains plug leads. Introducing a new loop tester for CATIV applications, the LT300 offers high current loop testing over a wide rangeof frequencies and supply voltages with simple, fast, two wire operation.
This data logger measures and stores up to 32,000 current loop readings over a 4-20mA d.c. measurement range. The data logger features a pair of screw terminals and is supplied complete with flashing red and green LEDs. The user can easily set up the logging rate and start time, and download the stored data by plugging the module straight into a PCs USB port and running the purpose designed software under Windows 2000, XP, Vista & 7. The data can then be graphed, printed and exported to other ap...
DSP2200 is a precision analyzer which is collected many kinds of modern high-tech achievements and it is widely used in the field of communication cable engineering measurement, acceptance, line maintenance, the accurate search of barriers , cable & electric features test, etc . The function of fault test is especially suitable for doing the fault accurate fixed-point and the range of fault includes the local cable of disconnection line , swinging cross , geogas , flooding water and insulation f...
These units receive 4-20mA process current inputs and provide isolated 4-20mA output signals. Each channel operates independently and is isolated from the others to prevent interaction between channels.
Portable: the wireless modular test and handhold terminal are light and handy and have powerful usage for floating testlHigh resolution screen: 4.3” high resolution colorized screen, display the real-time test data and result clearly.

The principle of operation is that an RF voltage appears across the terminals of a loop when it is placed in an electromagnetic field. This voltage is proportional to frequency for a given field strength. Therefore at Very Low Frequencies, the voltage is very small, and requires greater amplification.
