Megaohmmeter F4102 / 1-1M are designed to measure the insulation resistance of various electrical devices that are not energized, and can be used in all industries and agriculture. Technical characteristics Symbol of megaohmmeter Ф4102 / 1-1М and OKP codes are given in Table. 1. The range of measurements of insulation resistance, voltage values ​​at the terminals of the device with an open external circuit and sections of ranges with a relative error not exceeding 15 and 30% are given in table. 2. Accuracy class 1.5 according to GOST 8.401-80. The limit of the permissible value of the basic reduced error isundefined ± 1.5% of the scale length. The length of the scale of the megaohmmeter F4102 / 1-1M is not less than 88 mm. The limit of the permissible value of the additional error of megohmmeters caused by leakage according to the scheme for measuring currents of industrial frequency (interference): 350 μA (at measuring voltages of 500, 1000 and 2500 V); 50 μA (at a measuring voltage of 100 V), is equal to the limit of the permissible value of the basic error. The time to establish the testimony does not exceed 8 s. The charge time of an object’s capacitance of no more than 0.5 μF does not exceed 15 s. The time for establishing the operating mode does not exceed 4 s. The operating mode of F4102 / 1-1M megaohmmeters is intermittent: measurement - no more than 1 min., Pause no less than 2 min. Megaohmmeters F4102 / 1-1M are supplied from an alternating current network of voltage (220-33) ... (220 + 22) at a frequency of (50 ± 1) Hz, as well as from built-in chemical direct current sources (9 elements A 373). Power consumption from an alternating current main, power, no more than 10 V • A, from chemical current sources, consumption current, no more undefined 350 mA The built-in power supply before changing the batteries under normal conditions of use can provide up to 250 measurements with no more than 50 measurements per day. Megaohmmeter F4102 / 1-1M has a light indication: turning on and supplying high voltage - VN indicator; monitoring the performance of chemical current sources - indicator KP. Megaohmmeter F4102 / 1-1M maintains its operability at an ambient temperature of -30 to + 50 ° C and a relative humidity of 90% at a temperature of plus 30 ° C.
When powered by chemical current sources, climatic operating conditions are determined by the capabilities of the sources, but do not exceed those specified in this paragraph. Working position - horizontal position of the scale plane. Weight, no more: megaohmmeter, excluding chemical current sources - 1.9 kg; network power supply - 0.3 kg; case with accessories - 0.4 kg. Overall dimensions of megaohmmeter 305x125x155 mm. undefined
