HIGH-POTENTIAL DC AND AC METERS ITV-140R SERIES

The operating range of the measured currents is shown in Table 1.

Table 1

NOTE - Meters measure the average (rectified average) DC value and AC RMS value with a frequency of 50-60 Hz.

AC bandwidth, Hz - 0-1000

Input resistances of BV are given in table 2.

table 2

The limit of the absolute measurement error in the operating range of the
measured currents and temperatures is determined by the formula:

                                                                   D = 0.01 ∙ i _x + 5 e.m.r., (1)

                   where, i _x - the value of the measured current, mA; e.m. r. - unit of the least significant digit.

Discreteness of counting, mA - 0.001

Speed ​​- two measurements per second

Frequency range of the radio channel, MHz, 845-945

Number of frequency channels 16

Transmitter power, mW 1

Radio communication range (open space), m - 5-10

The meter can withstand an overload by a single current pulse with a duration of no more than 10 ms and an amplitude of no more than 150 A.

BV and MI are powered from built-in Ni - MH AA batteries with a voltage of 1.2 V and a capacity of 2.1 A ∙ h.

Supply voltage - 5V, duration of continuous work without recharging - at least 8 hours.
