Insulation Resistance Meters AMIC-5000

AMIC-5000 tester is designed to measure insulation resistance of power cables, transformers, motors and other electrically powered devices. Additionally the device allows for measurement of AC and DC voltages. Input circuits of the measuring devices are electronically protected from overloading, e.g. due to incorrect connection to the circuit being tested or incorrect use of input terminals.

Main characteristics are the following:

Insulation resistance measurement

• Measurement voltage:
  • *250, 500, 1000, 2500 y 5000 V
  • * From 250 to 5000 V, adjustable 50V steps
• On-line insulation resistance measurement or leakage current
• Automatic discharge of tested object’s capacitance after measurement of insulation resistance
• Direct measurement of one or two absorption coefficients
• Acoustic determination of 5 seconds time intervals that facilitates to take time characteristics during insulation resistance measurement
• Saving measured value of test voltages and selected times T1 , T2 y T3 ranging from 1... 600 seconds for the measurements of one or two absorption coefficients
• Indicator of the actual test voltage value during a measurement
• Measurement of alternating and direct voltages in the 0...600V range
• Memory of 999 measurement results with an ability to transfer the data to a PC
• Automatic selection of measurement ranges
• Powered by rechargeable battery pack
• Included with the device an external power supply for automatic battery charging to ensure prolonged battery life and optimal working conditions,
• Battery status indicator
• AUTO-OFF function

AC/DC voltage measurement
Range	Resolution	Accuracy
0...600V	1V	±(3%m.v. + 2 digits)
50Hz (sinusoidal shape with harmonic contents < 2%)

Leakage current reading
Range	Resolution	Accuracy
0...Ipmax	depending on range RISO	(-∆I- , +∆I+)
Ipmax  - maximum converter current 1,2 ± 0,2 mA
(-∆I- , +∆I+) - current reading accuracy calculated using the following formula:
∆I-= UISO.(1/R -1/(R+|∆R| )) ∆I+= UISO.(1/(R-|∆R| ) -1/R)
UISO - test voltage                     R - displayed insulation resistance value                     ∆R - resistance measurement defined for a particular measurement

Insulation resistance measurement

• Test voltage can be set in the range between 250V and 5000V with 50V intervals
• Test voltage accuracy (Robc[Ω] ≥1000*UN [V]): 0 +10% of the set value
• Voltage fluctuation due to temperature changes - better than 0,2% / ºC
• Measurement timesT1 , T2 and T3 for absorption coefficient measurement selected from the range between 1sec and 600sec with accuracy ± 1sec
• Measurement range according to EN 61557-2: R ISOmin ...5,0TΩ; R ISOmin =U ISOnom /1mA

0,0...999,9kΩ	0,1kΩ	±(3%.m.v. + 20 digits)
1,000...9,999MΩ	0,001MΩ
10,0...99,99MΩ	0,01MΩ
100,0...999,9MΩ	0,1MΩ
1,000...9,999GΩ	0,001GΩ
10,0...99,99GΩ	0,01GΩ
100,0...999,9GΩ	0,1GΩ
1,000...5,000TΩ	0,001TΩ
For measurements of limited converter current, the accuracy is not specified
