Important Information
CALMASTER works in conjunction with your own calibrated multimeter.
It quickly compares accuracy between the calibrated multimeter and
meter under test. It allows you to test and verify the various ranges for
AC/DC Voltage, Resistance and DC Current. Readings within ±5% of the
calibrated multimeter will prove the meter under test is deemed accurate
to BS ISO9001 standards.
PLEASE NOTE: Input sockets are provided for the calibrated meter and
meter under test. Controls are provided to adjust AC/DC voltages and
a switch to select functions. CALMASTER is powered from a switchable
115VAC or 230VAC supply. A RED neon indicates when AC power is on.
WARNING: DAMAGE OR INJURY MAY RESULT IF 115VAC IS SELECTED
AND CONNECTED TO A 230VAC SUPPLY. Safety fuses are provided for
input and output AC supplies
