Catohm - Earth measurement and continuity tester Application: Measurement of earth resistance. Highlight phase position and check the presence of earthing connection. Controls continuity of metal masses (buzzer). Features: Quick reading of conformity due to bicolor LCD Display (blue = OK/ red= no conformity). "Default loop" principle using for earth measurement in TT schema. Earth measurement with 3 1/2 digits LCD display (from 0 to 1999 Ω). Accuracy: ± (3% + 1 digit) for pure resistance, range 0 to 200 Ω at 23°C ± 5°C. Show presence of dangerous voltage (400 V - connection between phases). Full autonomy : no battery, power supply by plugging on 2P+T outlet. Composition: 1 device 1 roller with 7 m length cord M-921647 (non included into version DT-300-SE). 1 user manual
