DIGITAL MULTIMETER
(4½ DIGIT, HAND HELD)

-68 Rs. 2500/-

- 68 is a high performance, 4½ digit, hand held multimeter for measurements of DC and AC
voltages, DC and AC currents, resistances, capacitances and frequencies. Diode and transistor
hFE checking facilities have also been provided. High accuracy of ± 0.05% for DC voltages makes
- 68 useful for precision measurements.
- 68 incorporates dual slope A to D converter and CMOS technology for auto zero, polarity
and over-range indications. Full overload protection is provided.
- 68 is useful for production lines, laboratories, R&D organizations, maintenance and
repair jobs, industries, railways, defence establishments, communications, etc.
