Continuity Testing; Temperature Measuring - Ironside IMT 7000 Anleitung

4.15.4 Connect the red lead to the anode, the black lead to the cathode of the diode under testing.
4.15.5 You can get reading from LCD.
NOTE:
• The meter will show the approximate forward voltage drop of the diode.
• If the lead connection is reversed, only figure'0L'will be displayed.

4.16 CONTINUITY TESTING

When testing the circuit continuity, be sure that the power of the circuit
has been shut down and all capacitors have been discharged fully.
4.16.1 Connect the black test lead to the COM jack and the red test lead to the Ω jack.
4.16.2 Set the transform switch at the Ω
4.16.3 Put down the "FUNC." transformed at
4.16.4 Connect test leads across two points of the circuit under testing.
4.16.5 If continuity exists（i.e. resistance less than about 40Ω）, built-in buzzer will sound.
4.16.6 You can get reading from LCD.
NOTE:
• If the input open circuit (or the circuit resistance measured is higher than 400Ω), then the figure'0L' will be
displayed.
4.17 FREQUENCY MEASURING
4.17.1 Connect the black test lead to the COM jack and the red test lead to the Hz jack.
4.17.2 Set the transform switch at the Hz range position (or at the ACV range and the DCV range, put down the
"Hz%" to transform to Hz measurement).
4.17.3 Connect test leads across the source or load under measurement.
4.17.4 You can get reading from LCD.
4.18 DUTY CYCLE MEASURING
4.18.1 Connect the black test lead to the COM jack and the red test lead to the Hz jack.
4.18.2 Set the transform switch at the Hz range position.
4.18.3 Put down the "Hz%" to enter the DUTY measurement (or set the transform switch at the ACV range and the
DCV range, put down the "Hz%" to transform to DUTY measurement).
4.18.4 Connect test leads across the source or load under measurement.
4.18.5 You can get reading from LCD.

4.19 TEMPERATURE MEASURING

To avoid electrical shock, do not connect the thermocouples with the
4.19.1 Set the transform switch at the desired
4.19.2 The 'LCD' display will show the current environment temperature.
4.19.3 When measuring the temperature with thermocouple, 'K' type probe for this meter can be used. Insert the
black plug to the COM jack and the red one to the
area or surface of the object for measurement.
4.19.4 You can get reading from LCD.
NOTE:
• With better hermetization, the meter's temperature measured circuit and environment need a little longer time to
reach heat balance, and then accurate reading can be gotten.
