   MEGGER MJ159 (212159)   Description / Specification:    
MEGGER MJ159 100/250/500/1000 V Insulation Tester

The Megger MJ159 insulation tester is designed to give rapid, accurate and direct measurement of continuity and insulation resistance of domestic and industrial wiring, cables, transformers, motors, generators electrical machinery and appliances.
It is self-powered, and is suitable for use during installation and commissioning work as well as for service and maintenance applications.
Specifications.

Insulation Range.
Insulation Resistance: 0.1Ω - 2000 MΩ.
Nominal Test Voltages dc: 100 V, 250 V, 500 V, 1000 V.
Accuracy: 250 V, 500 V, 1000 V +30%, -0% maximum; 100 V, +40%, -0% maximum.
Midscale: 4 MΩ.
Short Circuit Current: 1.9 mA.

Resistance Range.
Range: 0.1Ω - 5000Ω.
Open circuit Test voltage: 3 V ±0.2 V.
Short Circuit Current: 2 mA ±10%.
Accuracy: ±1.25% of fsd on a 2.8 in. (71.1mm) arc length: [0.035 in. (0.9mm)].
Maximum Load Capacitance: 1μF with less than ±0.1” pointer movement.
Discharge: Up to 1μF capacitance is discharged from 1000V to less than 42.4 V in less than 4 seconds.

Safety Voltage Check.
Voltage measurement: 0.1 V - 600 V ac; the meter is RMS calibrated and average responding.
Safety voltage indicator: Indicates the presence of dc voltages, scaling is not the same as the ac meter; true dc voltage equals scale reading divided by 2.22.
Accuracy: 2.5% of full scale.

Power Supply.
Low voltage brushless ac generator, cranking speed between 130 rpm and 170 rpm.

dBc
dBc (decibels relative to the carrier) is the power ratio of a signal to a carrier signal, expressed in decibels. If the dBc figure is positive, then the relative signal strength is greater than the carrier signal strength. If the dBc figure is negative, then the relative signal strength is less than carrier signal strength.

Load Regulation
Load regulation is the capability to maintain a constant voltage (or current) level on the output channel of a power supply despite changes in the supply's load (such as a change in resistance value connected across the supply output).

Power Linearity
When changing the power level and measuring the differences (in dB) between actual and displayed power levels, the power linearity is ± half the span (in dB) between the maximum and the minimum value of all differences.

Settling Time
Settling time of an output device is the time elapsed from the application of an ideal instantaneous step input to the time at which the amplifier output has entered and remained within a specified error band, usually symmetrical about the final value.
