Description
- Safety Rules: Please read this manual carefully before use, it should not be used before placing the back cover back to avoid risk of electric shock, please do not touch lead terminal and circuit under test to avoid electric shock, please make sure the range select switch setting within the proper range before test, make sure the couple plug of lead inserted in the terminal tightly, when the tester is wet, do not use it or replace battery, please do not turn the switch during test, please do not test in flammable places since sparkles may cause explosion, please stop use when metal is exposed due to breakage of casing or testing wire, make sure the isolation skin of testing wire is intact before use, please make sure the testing wire has been removed from testing terminal and the range select switch is on off position before replacing battery, please make sure the range select switch is on off position after use, be extremely careful not to get electric shock as a maximum voltage of 50V is present between terminals (E-C and E-P) during measurement, do not apply voltage greater than 200V between terminals E-P, do not use this instrument to check an earth of a commercial power supply or for voltage measurement when making simplified measurement using an earth of a commercial power supply, 1 shows over range, select the higher range and re-test, replace battery when shown on tester or the battery indicator light is off to ensure testing accuracy, please remove the battery if not use it for long time
- Performance Features: Measuring range of earth resistance 0-2000 Q, measuring range of earth voltage 0-200V, 3 1 2 digit LCD display for more direct and convenient reading, size of LCD 68 x 55 mm (height of character is 35mm), response time is to measure earth resistance, about 5 seconds, measure earth voltage, about 2 seconds, withstand voltage AC 1500V, 1 minute between circuit and outer casing, overload protection on earth voltage, can withstand 300V AC (1 minute), on earth resistance, can withstand 200V AC (10 seconds), power supply 1.5VX 6 R6P AA SUM-3 batteries, dimensions 218 x 122 x 75 mm, weight about 900g (contain battery), working environment, working temperature 0 degree Celsius -40 degree Celsius, relative humidity 80 percent, storage temperature -10 degree Celsius - 50 degree Celsius, relative humidity < 85 percent, ensure accurate temperature 23 degree Celsius +5 degree Celsius relative humidity < 75 percent
- 20 Q Range: +-(2 percent rdg + 0.1 ohm) accuracy, 0.01 ohm resolution; 200 Q Range: +-(2 percent rdg + 3 dgt) accuracy, 0.1 ohm resolution; 2000 Q Range: +-(2 percent rdg + 3 dgt) accuracy, 1 ohm resolution; 200V Earth Voltage Range: +-(2 percent rdg + 4 dgt) accuracy; 0.1 v resolution
- Battery Replacement: Wien the battery voltage drop below proper operation range, the E symbol will appear on the LCD display and the battery need to changed, before changing the battery, set the range switch to off position, open the cover of the battery cabinet by a screwdriver, replace the old battery with the same type battery, close the battery cabinet cover and fasten the screw; Caution: Dispose the used batteries according to the rules, which are defined by each community
- Maintenance: This is a precise instrument and needs careful maintenance, don't open the back lid at will. Don't use it if the back lib not fixed, put it in the place dry and airiness if the meter will be leave unused for long term, don't change the inner circuit at Will or the meter maybe out of use, if there is any problem, contact with us please
