6.6.4.
High current measurements {optional with PM9245 or PM9244)
By means of the optional current transformer PM9245, alternating current with a value between 10A and 100A
can be measured with the PM2528, The frequency range of the current transformer is 45Hz — 1kHz.
Direct currents and alternating currents up to 31.6A can be measured by using the optional shunt PM9244,
The maximum frequency of the current to be measured is 1kHz.
High Current méasurements with the current transformer PM9245
— Select function. AY
— Select a range or the AUTO ranging mode.
— Select the HIGH RES mode or the normal resolution mode.
— Select the INT, EXT or MAN start mode.
— Connect the PM9245 to the 0 and A terminal of the PM2528.
Remarks
When the display shows dashes {e.g. -_——.—— uA} press START INT or MAN.
The transfer factor of the PM9245 is 1000:1 {10GA = 100mA).
The measuring range of the PM9245 is 10A up to 100A. The frequency range is 45Hz up to 1kHz.
For technical data of the PM9245, refer to page 24.
High current measurements with the shunt PM9244
— Select one of the functions V =, V~ or V~,
~ Select the correct range or the AUTO ranging mode.
— Select the HIGH RES mode or the normal resolution mode.
— Select the INT, EXT or MAN start mode.
— Connect the PM9244 to the O and V Qterminal of the PM2528.
Remarks
© There are two current ranges possible on the PM9244, viz, 10A or 31.6A. In both ranges the full-scale
output voltage can be switched to a value of 100mV or 31.6mV.
