Model: EM480D Measuring range: 20 ~ 200 ~ 2000 (M) Test voltage: 200 (V) Calibration cycle: 1 year Safety level: CAT III200V Maximum voltage: 200V Maximum resistance 2000 Tap resistance button: Yes Data hold: Yes Low voltage indication: Yes Battery powered: Yes Automatic shutdown: Yes Over range display: Yes LCD: Yes Overload : Yes Test button: Yes Backlight display: Yes Grounding Voltage Range Range 200V 0.1V (1.5%+3) Resistance Range Range 20 0.01 0.1 200 0.1 (2%+3) 2000 1 (2%+3) Display 3 1/2 unit symbol display Backlight function Yes Work Environment 5~40, relative humidity 75% Weight approx. 2514g/88.7oz Storage Environment -10~60, relative humidity 85% Power 6* 1.5V AA batteries (NOT included) Over Range Display Only figure "1" on the display Maximum reading 1999 readings Low Power Indication Yes Accuracy 3 1/2 Size 168*110*62mm / 6.6*4.3*2.4in Sampling rate 2.5 times/second Technical Indicators Within one year after the calibration accuracy, temperature of 23 5 , relative humidity: less than 75% 3 1/2 digits LCD display with a maximum reading of 1999. With line warning signs and buzzer alarm, automatic discharge safety without worry. LED gives red light and the buzzer sounds. It indicates that the resistance between "C" terminal and "E" terminal is out of the permitted range. With data hold function, low voltage indication and automatic shutdown function, low power consumption, more energy saving. Suitable for power system, electrical equipment equipment, outdoor testing, etc.
