Designed for the industry
The instrument is dedicated for companies and sites, in which continuous or random assessment of the insulation resistance is required as part of production. It is also perfect for automated production systems.
The meter can be installed in the distribution board, at the operator’s station (assembly or quality control bench), in the control cabinet or even in the rack enclosure. The measurement is performed by means of clamps, used to connect the test leads of the system, in which the instrument is installed.
Data transmission to a controlling device is carried out through the RS-232 interface or, at the customer’s request, any other.
- Selectable measurement voltage: 500 V or 1000 V
- Automatic discharge of the measured object’s capacitance upon completion of insulation resistance measurement
- Measurement current ≤2 mA
- Protection against measurement of live objects
- Two- or three-lead method of insulation resistance measurement
- Capacitance measurement after measurement of RISO
- Low-voltage measurement of resistance
- Data transmission to a controlling device through the RS-232 interface
- External power supply
- The instrument meets the requirements laid down by standard EN IEC 61557
The meter is designed for building in/permanent installation. It plays a Secondary/Slave role, meaning that it executes the commands issued by the Main/Master control device and it does not initialise the transmission on its own. It enables measuring the insulation resistance with the test voltage of up to 1000 V.
The scope set of functions of the meter is tailored to specialised applications. With the AutoRange function, available in two versions, the instrument can switch the test voltage dynamically and adjust it to the current conditions.
There are two measurement modes available: automatic (continuous) and manual (one-time). Under automated testing, the meter can be programmed to measure the capacity or not. In addition, the user may define the default function of the device as the measurement of insulation resistance (RISO), or low resistance (RX).
Response and communication
The functionality of the instrument is extended by digital input and output. This enables the meter to respond to the events in the system, in which it operates.
The meter is operated from the Main/Master control device by means of the MIC-RS-SCP serial communication protocol. It enables, for example, starting and stopping the measurement of resistance, reading the measurement result or changing the configuration of the instrument.
