Ac Measurements With Accessory; Resistance Measurements; Temperature Measurements - USAG 075 F Bedienungsanleitung

N.B.: in the current measurements, the instrument with respect to
ground shall not be set to voltages above 500V. Do not connect the
leads directly to any source of voltage when switched over in
current measurements. This may be dangerous, and the instrument
could be permanently damaged.
Alternating current measurements (AC) with accessory
• Position the rotary switch in the
measurement mode, the highest capacity, in the event that the current value
to be measured is unknown.
• Connect the black lead of the clamp to the "COM" bushing.
• Connect the red lead of the clamp to the "INPUT" bushing.
• Press the "FUNC" push-button to select A DC.
• Press the "RANGE" push-button to select the auto-range or manual
measurement mode.
• Take the measurement according to the diagram in figure page 74.
Note: a) if the "OL" message appears on the display, the value being measured is
greater than the maximum expected capacity.

Resistance measurements

• Position the switch on the capacity "
measurement mode, the highest capacity, in the event that the resistance value
to be measured is unknown.
• Connect the black lead to the "COM" bushing.
• Connect the red lead to the "INPUT" bushing.
• Press the "RANGE" push-button to select the auto-range or manual
measurement mode.
• Take the measurement according to the diagram in figure page75.
Note: a) with disconnected leads, the display will indicate " 1 ".
b) f the "OL" message appears on the display, the value being measured is
greater than the maximum expected capacity.
c) For values
stabilizing.
The resistance measurement on a circuit shall be always taken
without energy. Do not connect the leads to voltage sources. This
may be dangerous and could permanently damage the instrument.
Maximum overload voltage: 250V DC/AC RMS.

Temperature measurements

• Position the rotary switch on the "TEMP" capacity.
• Press the "FUNC" push-button to select the measurement mode "°C" or "°F".
• Connect the black pin of the sensor to the "COM" bushing.
• Connect the red pin of the sensor to the "INPUT" bushing.
• Take the measurement according to the diagram in figure page 77.
Note: when the sensor is not inserted, the instrument will indicate the room tem-
perature.
