The Metra Hit multimeter is a compact milliohm resistance meter plus digital multimeter and thermometer for the measurement of low-value contact resistance on aircraft outer skins (lightning protection, wick test), and for general low-resistance measurements.

The multimeter is also used for service and repair work performed on airplane and helicopter electrical systems (voltage, insulation, milliohm and temperature measurement)
In addition to its own multimeter functions for electrical quantities, the instrument also includes a mega-ohm measuring function with insulation test voltages of 50, 100, 250 and 500 V, as well as temperature measurement with Pt100 and Pt1000 sensors
Insulation resistance measurement 30 MOhm to 3 GOhm with adjustable test voltage of 50, 100, 250, or 500 Vdc
Milliohmmeter with 1 A measuring current and 200 mA measuring current
Kelvin connection (4-wire measurement)
Resistance measurement from 300 Ohm to 30 MOhm
Voltage measurement from 3 to 600 Vdc and 3 to 600 Vac with ±30.000 digits
LCD display with backlight
Frequency measurement from 300 Hz to 3 kHz
Memory for up to 1,200 measured values
Continuity and diode testing
Overload protection

CAT II-600V
