Model UT58A/B/C: OPERATING MANUAL
Note
l The test leads can add 0.1to 0.2 of error to the slow-
resistance measurement. To obtain accurate readings
in low-resistance, short-circuit the input terminals
beforehand and record the reading obtained (called
this reading as X). (X) is the additional resistance from
the test lead. Then use the equation:
measured resistance value (Y) – (X) = accurate readings
of resistance.
l If the input terminal short-circuit reading 0.5,check
the test leads for any looseness or other cause.
l For high resistance (>1M ), it is normal taking several
seconds to obtain a stable reading; select short test
leads for stable and precise readings.
l When the resistance is higher than the maximum range
or in open circuit condition, the Meter displays "1".
l When resistance measurement has been completed,
disconnect the connection between the testing leads
and the circuit under test.
