Accessories
(See also table “Order Information” below)
The following accessories, some of which are included as
standard equipment, are recommended for use with the METRA
HIT 27 or METRA HIT H+E
CAR respectively:
Mains power battery charger with
broad range input
NA HIT 2x: AC 90 ... 250 V DC 5 V
NiMH quick charger Z206D
Microprocessor-controlled quick charging unit for 1 to 4 NiMH or
NiCd storage batteries, AA or AAA type (micro and/or mignon)
with a 100 ... 240 V AC power supply unit and 10 ... 15 V DC
motor vehicle charging cable.
Milliohm Measurement with Type KC4 Kelvin Clips
Kelvin clips are suitable for establishing contact between the
METRA HIT 27 and low-resistance devices under test. They com-
pensate for influence resulting from cable and contact resistance.
The KC4 set includes two clips with insulated, twist-resistant jaws
and good clamping action. They can be used for establishing
contact with very fine wires, up to rails and rods with a maximum
diameter of 15 mm. 4-pole connection is highly advisable for the
measurement of values of less than 30 .
Milliohm Measurement with Type KC27 Kelvin Probe
Same usage as KC4, but with two 2 spring loaded steel tips for
piercing insulation coatings (e.g. on the outer skin of aircraft) and
oxide layers (e.g. at oxidized battery contacts), in order to assure
good contact for milliohm measurements, as well as for current
and voltage measurements.
Temperature Measurement with Z3409 / Current Measurement with CP330
The Z3409 is just one
of many temperature
sensors which can be
selected from a wide
ranging product spec-
trum. For further infor-
mation regarding tem-
perature and current
sensors, as well as
other accessories,
