Dc Current Measurement - HT Instruments HT62 Bedienungsanleitung

4.3.8. DC Current measurement

Maximum input DC current is 10A (input 10A) or 600mA (input mAA). Do
not measure currents exceeding the limits given in this manual. Exceeding
voltage limits could result in electrical shocks to the user and damage to the
instrument.
Fig. 9: Use of the instrument for DC current measurement
1. Cut off power supply from the circuit to be measured.
2. Select position A
3. Insert the red cable into input terminal 10A or into input terminal mAA and the black
cable into input terminal COM.
4. Connect the red lead and the black lead in series to the circuit whose current you want
to measure, respecting polarity and current direction (see Fig. 9).
5. Supply the circuit to be measured. The display shows the value of current.
6. If the display shows the message "O.L", the maximum measurable value has been
reached.
7. When symbol "-" appears on the instrument's display, it means that current has the
opposite direction with respect to the connection in Fig. 9.
8. To use the HOLD, RANGE, MAX MIN and REL functions, see § 4.2.
