770 serial tong-type ammeters that the ideal industrial corporation of U.S.A. introduced not long ago adopt the double display to be designed, not used the limiting of the space, receive the masses of field engineers' favor, have become the ideal choice used in limited site measuring of space.
Serial 770s tong-type ammeter is with patent for double display design,it hand in /measure DC current highest until 1000A. The functions of 770 serial tong-type ammeters also include: The rms value is measured, maximum / minimum / crest value measures ( 1ms) , capacitance measurement, it possessed all daily functions of 3 3/4 multimeters at the same time. 770 serial tong-type ammeters reach above 30V to carry on the automatic Audible and Visual Alarm in the voltage, such functions as it is not enough to point out that a sound briefs on turning on, data hold, automatic shutdown, battery in a poor light at the same time. This product adopts the bottom of patent and shows designing, reading is more convenient; The unciform toper gate is designed the separation suitable for narrow and small space and cable. This product adopts hold key of the data and thumb to sow one, benefit one-handed operation. 770 serial tong-type ammeters accord with CAT IV-600V, CAT III-1000V pressure tight norm, the gate size is 51mm. The quantums of 770 serial tong-type ammeters: Alternating current 400.0/1000A, 1.7% of basic precision; DC current 400.0/1000A, 1.5% of basic precision; Alternating current voltage 400.0m/4.000/40.00/400.0/750V, 1.2% of basic precision; Direct-current volts 400.0 m/4.000/40.00/400.0/1000V, 0.5% of basic precision; 400.0/4.000 of the k/40.00k/400.0k/4.000M/10.00M Ω in resistance, 1.0% of basic precision; Electric capacity 4.000μ / 40.00μ / 400.0μ / 4.000mF, 3.0% of basic precision.
