Resistance Measurements - PeakTech 1650 Manual De Instrucciones

4. The most accurate reading will be obtained by keeping the
conductor across centre of the transformer jaws.
5. The reading will be indicated on the display.
6. Reduce the range setting if too high until a satisfactory best
resolution reading it obtained.

6.3. Resistance measurements

WARNING! Attempting resistance or continuity measurements on
live circuits can cause electric shock, damage to the instrument
and damage
measurements must be made on de-energized circuits only for
maximum personal safety. The electronic overload protection
installed in this instrument will reduce the possibility of damage to
the instrument but not necessarily avoid all damage or shock
hazard.
1. Turn off any power to the resistor to be measured. Discharge
capacitors.
measurement will cause inaccurate readings and could
damage the meter if exceeding the overload protection of 250
V DC or AC.
2. Insert the black and red test leads into the COM and V/ input
terminals respectively.
3. Select the desired ohm () range.
4. Select Ω by pressing MODE-button
5. Connect the black and red test probe tips to the circuit or
device under test, making sure it is de-energized first.
6. Open circuits will be displayed as an overload condition (OL)
7. Test lead resistance can interfere when measuring low
resistance readings and should be subtracted from resistance
measurements for accuracy. Select lowest resistance range
and make the test leads short together.
