- Page 2 MPO-02 is a measuring device which serves to measure low resistance, and the voltage drop across the protection circuit to the alternating current of more than 10 A AC. The device allows to determine the exact value of resistance of the protective circuit and voltage drop at the protective circuit according to the cross-section of protective conductor.

Measurement Mode Ω Switch Mode switch (6) to Ω. Retract into to the socket (230 V, 50 Hz) the power cord of the measuring device (1). On the rear of the device lights up the green light of the Timer (5). The display shows the resistance measurement of the protective circuit in cross-section 6.0 mm². - Page 6 If the resistance value of the protection circuit for set protective conductor cross-section exceeds permitted value by STN/ČSN 60 204-1 (see table), the device with an audible alarm warns the illegal value of the resistance. Resistance value greater than the highest value of the measuring range, i.e. higher than 1,999 Ohm is indicated on the display by illumination of eights –...
- Page 7 Selection of the various protective conductor cross-sections is performed using the selecting button MODE (7). After its pressing and holding for approximately 1 second are successively elected various protective conductor cross-sections. Selection of different cross-sections is signaled acoustically. If the value of the voltage drop on the protection circuit for set protective conductor cross- section exceeds permitted value by STN/ČSN 60 204-1 (see table), the device with an audible alarm warns the illegal value of voltage.
