Auto-discharge function
This is a function to discharge capacitance stored in the circuit
under test automatically after testing. Discharge condition can be
checked on the voltage monitor. This function will be canceled
when removing the test leads 2 sec. or more before discharge
completes.
(6) Set the Range switch to “OFF” position, and remove test leads
from the instrument.
Note)
● The voltage warning mark stays on during a measurement and it
blinks when voltages of AC/DC 30V or higher exist on the circuit
under test.
● When measuring low resistances (if currents larger than the
rated current are output) over a long period of time, KEW3126
consumes large power and will overheat. When this happens,
further tests are automatically inhibited and the over-temperature
symbol
appears on the display. The instrument must then
be left cool down. Testing shall be resumed when symbol
disappears.
Short-circuit currents at a start of measurement may get lower
when the “ ” symbol appears.
● Depending on the ambient temperature or measured resistances,
the “ ” symbol may appear and interrupt a PI measurement.
