PHILIPS Universal Measuring Instrument P 817 00/01 is eminently suitable. It is the ideal measuring instrument for use in the smaller repair shops or at the customer's home, owing to its small dimensions and to the fact it does not require any mains supply. - Page 4 Current Measuring Position Position consumption range Of Sk1 Of Sk2 Scale or voltage Sensitivity loss at full deflection 60 mV * 0 – 60 mV 33,300 position Ω/V 0 – 3 V 0 – 12 V 12 V 30 µA 0 –...

TRANSPORT The right-hand knob (Sk ) is provided with a green dot. Whenever the instrument is transported, set this knob to the position marked with the green dot. In this position the galvanometer is short-circuited. The same precaution should he taken when the meter is to be sent to the repair shop. -

MEASURING A. Direct voltage (A V scale) Set knob Sk to position " ". Set knob Sk to position "1200 V" (highest voltage range, to prevent overloading) and connect the measuring leads to the sockets + and –. 3. Now connect the measuring leads to the voltage source to be measured and set knob Sk to that measuring position that is most suitable to provide an accurate reading of the voltage in question. -
Page 7: Alternating Current
Alternating current (A V scale) Set knob Sk to position "~". Set knob Sk to position "3 A" (highest current range, to prevent damage to the meter) and connect the measuring leads to the sockets + and -. Now connect the measuring leads to the current circuit to be measured and then set knob Sk that measuring position that is most suitable to provide an accurate... - Page 8 REPLACEMENT OF BATTERIES Place the meter upright on a table, loosen the two screws in the cover plate (at the rear) three-quarter turn and remove the cover plate (by Aiding it upwards a little and then pulling it forward). The batteries can now be removed from the meter casing (if necessary, the smallest with the aid of a thin screwdriver) and replaced by fresh ones? Make sure that the + terminals of the batteries make contact with the contact springs marked + in the meter casing.

C’. Alternating-voltage measurements The alternating-voltage ranges are mainly used for measuring the L.F. output voltage of some apparatus, or for examining the voltages of the mains transformer, etc. D'. A.C. Measurements It is sometimes desired to measure the current consumption of some apparatus.
