The S1-552 is an advanced 5kV insulation tester with a high output current and many time-saving features. A large, analog/digital LCD shows resistance valves up to 5 T%u03A9 and incorporated a timer and other test information. The output current, of up to 5mA, speeds up testing by charging capacitive loads quickly.
The 5 and 15-kV Megohmmeters are high-voltage, line operated instruments that can be used on all types of insulation tests ranging from 500 volts to 15 kV.
With over twenty 1-kV models to choose from, selecting the proper Megger insulation tester can appear a bewildering task at first. Actually all the process requires is a little organization. All Megger insulation testers perform essentially the same test in fundamentally the same manner %u2014 accurately and reliably. Refinements and added features, however, separate one model from another in application and operator appeal.

Having both battery and mains operation and four selectable DC test voltages (500V, 1kV, 2.5kV & 5kV), this tester measures insulation resistance. The large, clear analogue scale also displays AC or DC voltage up to 1000V. Latching test switch allows hands free testing.
With full over-voltage and over-current protection for measurements and 8 hours operation from rechargeable Nicad batteries, the E3511 comes in a carry case. Standard accessories include locking 2m test leads with prods and clips. |

When measuring EMC conducted emissions from the equipment-under-test, (EUT) most standards specify a LISN (or artificial mains V-network) to couple the RF from the cable, and to provide a repeatable impedance at the measured frequencies. All LISN's fully comply with the relevant standards and feature a rigorous, individual calibration.

From Megger, these highly accurate, easy to operate instruments measure resistance with resolution as fine as 0.1 micro-ohm. Digital micro-ohmeters and DLROs measure contact resistance of switch and circuit breakers, aircraft frame bonds, and rail and pipeline bonds just to name a few of the applications. Megger has models available for testing using test currents from 0.5 mA to 100 amps covering a multitude of applications that require precise low-resistance measurements.

QT25 uses a unique method to detect exact PCB short circuit locations and also pinpoint the shorted components/tracks. Ideally PCB tracks are suppose to have zero resistance, but in actual conditions they have small resistance. The exact location of the short is where the instrument reads the lowest value of resistance and this resistance could be detected with a sensitive instrument like QT25, even in power planes.
QT25 can also be used in measuring the contact resistance of switches and relays in its milli-ohm mode.
QT25 is designed to apply a drive voltage of less than 200 millivolts, while detecting shorts in the populated PCBs, so as to avoid turning on the semiconductor devices inside the circuit, which could lead to misleading results.
There is a composite '16 character alpha numeric backlit LCD display' to show the Resistance range selected, Offset indication, Resistance value, and also the Units.
1. 4 wire resistance measurement
