HIGH RESISTANCE HIGH SPEED MEGOHMMETER

 DB602 Megohmmeter Insulation Tester.

DB602 Megohmmeter Insulation Resistance Meter is designed for use in applications such as automatic testing insulation resistance of capacitors in production lines.
The Megohmmeter is microprocessor controlled. 
The menu driven bright back-lit LCD display enables quick, logical and easy operation.
The display can show the leakage current or insulation resistance as a function of time as an X-Y graph or a bar graph simulating an analogue meter.



DB602 Megohmmeter Insulation Resistance Meter
  • The bar graph can use auto-scaling or 8
    fixed scales with two decades each.
  • The instrument can be programmed to automatically perform timed test sequences.
  • Each sequence may consist of up to 12 test steps, either high current charging, normal charging, or a measurement. 
  • Sequences may last up to 60 min.

The DB602 Megohmmeter Insulation Resistance Meter also features pre-programmed sequences, for example a sequence for Quality Control, that charges until a minimum insulation resistance is reached, then discharges automatically.

Programmable delay of measurement: Up to 10sec in steps of 1 msec after external triggering.

The measurement results may be used for BIN sorting with one out of five limit sets.

The instruments are fitted with both standards IEEE (GPIB) and RS232 Interfaces.
Also an optically insulated Handler/Limits Interface is included.

The high speed of the Megohmmeters: 52 msec between measurement results give the possibility of implementing prediction intelligence in an external PC for very high-speed production test of capacitors

The high test speed is supported by the instruments in other ways: First of all by the low input impedance 10kOhm for test current above 10nA, and 1MOhm for test current below 10nA.
The special 25mA or 100mA charge mode speeds up insulation testing of large capacitors significantly.

Automatic check of contact failure for capacitors and capacitive elements like cables is a feature implemented for high volume production. The contact check does not increase the test time.
