EMERSON - PN2990 - 8005 HORIZON 230 VAC 1 HP DRIVE BRAND-NEW AC SERVO DRIVE

1. Measurement of DC current. Insert the black pen into the "COM" hole first. If measuring a current greater than 200mA, insert the red probe into the "10A" socket and turn the knob to the DC "10A" position; If measuring a current less than 200mA, insert the red probe into the "200mA" socket and turn the knob to a suitable range within 200mA DC. After adjustment, you can measure it. String the multimeter into the circuit and maintain stability to read. If it displays "1.", then the range needs to be increased; If a "-" appears to the left of the value, it indicates that the current flows from the black probe into the multimeter.
Measurement of AC current. The measurement method is the same as 1, but the gear should be set to the AC gear. After the current measurement is completed, the red pen should be inserted back into the "V Ω" hole. If you forget this step and directly measure the voltage, haha! Your watch or power supply will soar into the sky in a wisp of smoke - scrapped!
3, Measurement of resistance
Insert the probe into the "COM" and "V Ω" holes, rotate the knob to the required range in "Ω", and connect the probe to the metal parts at both ends of the resistor. During measurement, you can touch the resistor with your hand, but do not touch both ends of the resistor with your hand at the same time. This will affect the measurement accuracy - the human body is a conductor with high but limited resistance. When reading, it is necessary to maintain good contact between the probe and the resistor; Attention unit: In the "200" gear, the unit is "Ω", in the "2K" to "200K" gear, the unit is "K Ω", and in the "2M" or above gear, the unit is "M Ω".
4, Measurement of diodes
A digital multimeter can measure light-emitting diodes, rectifier diodes... When measuring, the position of the probe is the same as that of the voltage measurement. Turn the knob to the "" position; Connect the red lead to the positive pole of the diode and the black lead to the negative pole, and the forward voltage drop of the diode will be displayed. The voltage drop of Schottky diodes is about 0.2V, ordinary silicon rectifier tubes (1N4000, 1N5400 series, etc.) are about 0.7V, and light-emitting diodes are about 1.8-2.3V. If the probe is replaced and the display shows "1.", it is normal because the reverse resistance of the diode is very high, otherwise the tube has been broken down.
