Universal current tongs HT71 can be used in many instances, but it is more frequent due to the conditions of the increased safety. Model HT71 measures alternating current, voltage of alternating and direct current, resistance, frequency and carries out the test of electrical conductivity. This model is delivered with the tongs (seizure) with the variable slope angle. They completely correspond to standard [E]N 61010-1, CATIV of 600V[i] CATIII 600V for the stress.

Basic functions

• the retention of the peak values
• automatic turning off of the nourishment
• the manual regime
• the measurement of alternating current
• the measurement of the voltage of alternating and direct current
• the measurement of the resistance
• the measurement of the frequency
• the test of the electrical conductivity
