Megohmmeter М1423.1

The megohmmeter M1423.1 is used to measure the insulation resistance of AC networks that are energized and do not have a galvanic connection to the DC network, as well as de-energized DC and AC networks. The devices are vibration-proof and shock-proof, made in splash-proof housings. Megaohmmeter м1423.1 meets the requirements of the Technical Regulations on the safety of maritime transport facilities, the Russian Maritime Register of Shipping Rules, the Technical Regulations on the safety of inland water transport facilities, the Russian River Register Rules and TU25-04.3913-80. Megohmmeter М1423.1 technical characteristics Protection class IP 54. Rated voltage 127, 220 or 380 V. Rated frequency 50 - 500Hz. Accuracy class 2.5. Overall dimensions М1423.1, М1423: 80 x 80 x 126 mm; Measurement range - from 0 to 5 MΩ. The maximum permissible basic error in the measurement range of the scale length is ± 2.5%. Internal resistance - not less than 240 kOhm. The limit of additional permissible error caused by a change in the ambient temperature from normal + 20 ± 5 ° C to a temperature in the range from -10 ° C to + 50 ° C for devices for every 10 ° C of temperature change is 50% of the designation of the accuracy class. The limit of the permissible additional error М1423.1 caused by a change in the supply voltage by ± 15% of the nominal is equal to the limit of the permissible basic error. The limit of permissible additional error caused by a change in the operating position (tilt) of the device from the normal in any direction by 45º - ± 1.25% of the scale length. The limit of the permissible additional error and half of the swing range of the pointer when exposed to one-component vibration at a maximum acceleration of 19.6 m / s2: - in the frequency range from 1 Hz to 60 Hz - ± 2.5% of the scale length; - in the frequency range from 60 Hz to 120 Hz - ± 5% of the scale length. Isolation test voltage between electrical circuits and the case, as well as between the supply and measurement circuits - 2 kV. Insulation resistance of electrical circuits relative to the case, as well as between circuits - not less than 20 megohms. The time to establish the readings of the M1423.1 indicating device is no more than 3 s Scale length - 110 mm. The warranty period is 2 years. Service life - 25 years. Controlled network parameters: - Controlled network voltage - 127 V; 220 V; 380 V; - nominal frequencies - 50 Hz; 400 Hz. Weight - no more than 1 kg. Megohmmeter М1423.1 operating conditions Normal ambient temperature - from + 15 ° С to + 25 ° С. Normal relative humidity at + 25 ° С - from 30% to 80%. Operating temperature of the ambient air - from -40 ° С to + 50 ° С. Operating relative humidity at + 50 ° С - up to 100%.
