  • Precision AvoMeter

    An accurate laboratory instrument to provide an accurate and stable local reference or transfer standard for industrial and laboratory engineers. It meets the requirements of Section 6 of BSS 89/1954 for precision-grade instruments.

    A test certificate is provided for each instrument.

    Two models are known. Mk. 1 with wire-wound resistors and Mk. 2 with blue Welwyn-type resistors.

    Ranges:  
    DC Voltage: 1.5 to 1500 V in 9 ranges
    DC Current: 1.5 mA to 15 A in 9 ranges
    AC Voltage: 3 to 1500 V in 8 ranges
    AC Current: 3 mA to 15 A in 8 ranges

    Two 7" scales calibrated 0 to 150 and 0 to 30 cover both voltage and current measurements.

    The accuracy on AC voltage and current ranges is 0.75% of FSD (form factor of 1.11). This accuracy is maintained for audio frequency tests up to 1 kHz on ranges up to 3OOV.

    Sensitivity 100 Ohms/Volt on DC and AC except for 3V AC range which is 50mA fullscale.
