Inspection and Installation
• Before connecting test cables, be sure to switch off the instrument.
Power switch is in Off position, otherwise touching the output ter-
minals on the rear panel may result in personal injury or death due
to electric shock.
• To avoid electrical shock, before testing, please make sure the rat-
ing values of the testing cables, and do not measure the current
that higher than the rating value. All test cables shall be capable of
withstanding the maximum short circuit current of the instrument
without causing overheat.
• If several loads are provided, each pair of load wires shall safely
withstand the rated short circuit output current of the power supply
under full load.
• Do not short the battery when connecting or disconnecting the bat-
tery testing circuit. Short circuit may cause severe accident.
• Because the instrument can be used to sink current, hazardous vol-
tages from an external energy source such as a battery may be
present on the output terminals even with the instrument power off.
Provision must be made to disconnect the external energy source
before touching the output or sense terminals.
• Always use test cables provided by ITECH to connect the equip-
ment. If test cables from other factories are used, please confirm
the maximum current that the test cables can withstand.
• During wiring, check that the positive and negative poles of the test
cables are properly and tightly connected. Do not connect the posi-
tive pole and disconnect the negative pole.
• Ensure that the output terminals are either insulated or covered us-
ing the safety covers provided, so that no accidental contact with
lethal voltages can occur.
Specification for Test Cables
Test cables are not standard accessories for the instrument. Please select op-
tional red and black test cables for individual sales based on the maximum cur-
rent value. For specifications of test cables and maximum current values, refer
to A.1 Appendix→Specifications of Red and Black Test Lines.
Connecting the DUT (Local Measurement)
The instrument supports two kinds of wiring methods with the DUT: local meas-
urement and remote measurement (SENSE). The default test mode is local
measurement.
The connection diagram and steps of local measurement are as follows:
