Automatic choice of range of measurement!!!
Automatic calculation of unit resistance of soil!!!
The earth resistance meter TsS4107 intended for measurement of resistance to spreading of current of grounding devices, determination of unit resistance of soil with automatic calculation of its value, measurement of resistance of conductors of land part of a grounding device.
Indication of results of measurements - alphanumeric on the liquid crystal indicator with illumination (further - the LCD indicator).
Measurement range - from 10 mΩ to 20 kΩ.
Legitimate value of resistance of electrodes for the measured resistance of Rizm is given in table 1.1 (where by RP1, RP2 - resistance of potential electrodes, RT1, RT2 - resistance of current electrodes).
|The measured resistance||Range of a legitimate value of resistance of electrodes|
|RP2 or sum (RP1 + RP2)||RT2 or sum (RT1 + RT2)|
|10 mΩ - 1 Ω||0 - 5 kΩ||0 - 1000 · Rizm
but no more than 50 kΩ
|1,001 Ω - 20 kΩ||0 - 50 kΩ|
Tension of measuring current on current clips of the measuring instrument no more than 36 V virtual values. A circuit current of the measured resistance no more than 350 mA.
Frequency of measuring current (128 ± 6) Hz.
Ambient air temperature of operating conditions of use of the measuring instrument from minus 10 ºС to plus 55 ºС.
Measuring instrument power supply - eight Ni-MH of accumulators of a standard size of AA, of 1,2 V, with a capacity not less than 2 And / h.
Consumption current from accumulators no more than 1,0 And.
Time of establishment of an operating mode - directly after inclusion.
The measuring instrument allows to make:
a) a charge of accumulators from the network power supply unit or an onboard network of the car via the lighter connector;
b) indication of process and degree of a charge of accumulators;
c) automatic shutdown within (90 - 120) s after completion of work;
d) storage in memory of results of 50 previous measurements;
e) automatic disconnection from electric power supply at undervoltage of accumulators lower than 8,8 V;
g) indication: availability of third-party tension on potential clips over 7 V; exceeding of admissible resistance of electrodes;
h) automatic choice of a unit of measure;
i) automatic calculation of unit resistance of soil.
Accuracy rating of the measuring instrument - 2,5 in accordance with GOST 8.401.
Limits of the allowed relative main measurement error are equal ± 2,5% of the measured resistance.
Operating mode - repeated and short-term, measurement to 1 min, break time to reclosing is not limited.
