Measuring ground resistance M416/1 (M416 1, M4161, M416-1)

For measurements of earth resistance in the mines, including hazardous gas and dust.
Measurement range: 0.1 ohms to 1000 ohms.
Accuracy: 5%

Measuring ground resistance M416/1 is designed to measure earth resistance in the mines, including hazardous gas and dust.
In terms of resistance to climatic and mechanical effects unit measuring ground resistance M416/1 corresponds to GOST 22261-76 (group 4) extended operating temperature range of -25 to +60 ° C relative humidity of 98% (at 35 ° C).
Permissible basic error of the meter (in percentage):
δ = ± [5 + (N/Rx-1)]
where N - the final value    measurement range, Ohm; Rx - the measured resistance in ohms.
Error of the instrument measuring ground resistance M416/1 does not exceed the permissible basic error when changing the resistance of the probe and auxiliary earth electrode within the limits given in the table.
 
Measuring range, Ohm
The resistance of the probe and auxiliary earth electrode, Ohm
0.1 ohm - 10 ohms
0-250 ohm
0.5 Ohm -50 ohms
0-500 ohm
2 Ohm -200 Ohm
0-1000 ohms
10 Ohm - 1000 ohms
0-2500 ohms
