2Specifications
Resistance range ..................0.01 Ω to 1 kΩ in 0.01 Ω steps
NOTE: On all ranges 0.01 Ω up to 100 Ω, the maximum applied voltage is proportional to the set point, keeping
the current at or below the maximum specified.
Residual resistance .......................Less than 60 mΩ (< 12 mΩ / decade).
Residual resistance stability......... Less than 3 mΩ.
Power rating ................................... 1 watt per resistor. Metal film resistors are used throughout.
Voltage rating .................................Maximum 100 V DC, 70 V AC RMS.
Current rating ................................. Maximum 1 A DC, 0.7 A AC RMS.
Temperature coefficient ................ 50 ppm/°C.
Connections ...................................2 x 4 mm active safety terminals. A third safety terminal
is to enable the case to be earthed or connected to
either output.
