Multi-Channel Type On-Off Recorder HK-8
Multi-Channel Type On-Off Recorder HK-8
A Dependable Analog Type Recorder for Recording Operation Status of Contacts
This is a discharge-recording type time measuring instrument to measure and directly read the ON-OFF status of the contacts such as open / close times of a circuit breaker, disconnecting switch and various types of switches or operating time of an electromagnetic type relay. This instrument is compact and portable, and hence, it is suitable for site commissioning test and periodical inspection.
SALIENT FEATURES
- 1/ Strong against High Voltage Induction
This instrument can be used without any interference due to inductive voltage in the vicinity of 500kV System. - 2/ Provided with a High Capacity Operating Circuit
The Operating Circuit with a resistance load switching capacity of AC 200V 15A / DC 100V 10A is provided. - 3/ Compact, Light-weight and Easy Operation
One switch operation makes possible both paper forwarding and recording. - 4/ High Measurement Accuracy
Measurement accuracy of approx. 0.001 seconds can be achieved thanks to pure electrical recording and no mechanical parts.
