    (or simultaneously) records data in the internal memory at regular time intervals. This manual assists in the installation and use of C-80 type measuring instruments and helps to obtain the best service from it. Carefully read this manual before connecting the equipment to avoid incorrect use which may cause irrevocable damage.

    The instant maximum, minimum values, recorded values and THD alarms can be displayed. Power supply: The C-80 Analyzer is powered by two standard 1.5 V AA type batteries. The independent operating period is about 200 hours. The equipment switches itself off after 5 minutes if not recording.

    500 V AC. between voltage inputs. Maximum measurable current: according to clamps used. Whenever a clamp is connected, the C-80 auto-detects the clamp and stores the configuration (Current primary) of the clamp automatically in the setup. This does not occur with the CP-5 clamp. This is due an external transformer that has to manually programmed.

  • Page 6: Values Measured In Balanced Three Phase Mode And Single Phase Mode

    3.1.- Values measured in balanced three phase mode and single phase mode In three phase mode, the three phases must be connected in the correct fashion plus a current clamp to measure current. The C-80 measures power consumed. Balanced three phase value Single phase value...

  • Page 7: Connection Diagrams

    NOTE: The L1 and L2 voltage terminal connections take the measurement. The L3 terminal → → is for checking the turn direction of the phases (1 If the phases are incorrectly connected the C-80 will display the prescribed turning direction. (See section 3.5 Presentation of data on the display).

  • Page 9: Connecting A Current Clamp

    C-80 is a two quadrants instrument. The user does not need to concern himself with the direction of the current clamp. If the direction of the current is unknown, the C-80 internally changes the direction so that it always measures power consumed 90º...

  • Page 10: Starting Measuring With The C-80

    If this is not done, it may mean that the measurements are not correct. The C-80 Analyzer has an energy saving system. If no key is touched for 5 minutes, the C-80 switches itself off. This does not occur if the equipment is recording.

  • Page 20: Registering Menu

    The C-80 ANALYZER has the option to record the measurements and store them in a non- volatile rotating memory with a capacity of up to 33 recordings. The C-80 has an option to register up to 33 measurements and store them in the non-volatile rotating memory. It has a rotating file, meaning that once the 33 recordings are full it will continue registering new data in the oldest position.

  • Page 21: Timed Registers

    15 minutes. 4.6.2.- Instant registering THE C-80 ANALYZER allows instant registers of the measurements, i.e. taking a "photo" of the present measurements The values registered will be those measured instantaneously The variables will be the same as the timed registers except that the maximums and minimums will be those on the display and not those from a preset period.
