Please read the relevant information carefully and observe all the Warnings and Notes strictly. Limit 20 is a clampmeter/multimeter for professional use. The instru- ment have autorange and the display have large digits, shows rotary switch position witch makes this instrument easy to handle for the user. - Page 8 English test, adhere to the following rules: • Before using the Meter inspect the case. Do not use the Meter if it is damaged or the case (or part of the case) is removed. Look for cracks or missing plastics. Pay attention to the insulation around the connectors.

Never attempt an in-circuit current measurement where the vol- tage between terminals and ground is greater than 600 V. 1. Set the rotary switch to 2/20 A or 200/400 A position. 2. Open the jaws and center one of the conductor. Only one con- ductor at each time can be measured. -

English Note • The test leads can add 0.1Ω to 0.3Ω of error to resistance mea surement. To obtain precision readings in low-resistance measure- ment, that is the range of 200Ω, short-circuit the input terminals beforehand and record the reading obtained. This is the additional resistance from the test lead. - Page 11 4. Connect the test leads across with the object being measured. The buzzer sounds if the resistance of a circuit under test is less than 50Ω. Replacing the Battery (see fig 4) 1. Disconnect the connection between the testing leads and the cir- cuit under test when battery indicator appears on the display.
