  • Notes

  • The AVO Test Set Multirange No. 1 (High Sensitivity) is a specialised version of the AVO meter series with high sensitivity comparable to the Model 8 Avometer. It features an improved scale plate design for easier reading and a push-button change-over switch for range selection.
    This test set is identified by the NATO part number 6625-99-105-7050 and was made as a smaller, more compact multimeter variant primarily for military use. It offers multiple voltage and current ranges and is noted for its robustness and sensitivity, measuring down to 50 microamperes (µA) in some configurations.
    The Test Set No. 1 shares design traits with the Model 8/9 Mk II versions but includes differences like additional ranges, no dB scale, and protective fuses in later versions.
