Other measurement and diagnostic capabilities include phase rotation, voltage detection, continuity check, diode test, in-rush current, and low-pass filter. The CW10 possesses a joystick that allows the user to select the preferred diagnostic function. The display is backlit when clamping and contains a 3.5 digit and bar graph display. The CW10 meets CAT IV 600 V and CAT III 1000 V safety standards and is CE-rated. Standard accessories provided with the unit are (1) 9V battery, test leads, soft case, and instruction manual.
