Million Megohm Meter |
|
Model : Insulations Testers |
 |
|
INTRODUCTION
This series of Million Megohm Meters are designed to test electronic components
such as paper Capacitors, Plastic Capacitors, Ceramic Capacitors, Insulators,
Semi Conductors, Switches, Connectors, transformers, Motors etc. as per I. S. I.
recommendations. The instruments have facility for
checking insulation resistance in the range of 1 meg ohm to 10 million meg ohm
after one minute of charging. Ultra stabilized power supply (.001% short term
drift) permits measurements of intrinsic value of insulation resistance if
required, even with capacitive loads. Separate push button controls and visual
indicators for "Charge", and "Discharge" function are ideally suited for rapid
and safe testing of components in a factory. Maximum output current has been
limited to safe value to eliminate the risk of serious shock to operators. The
instruments are available in five models as per specifications given overleaf. |
