        ST-1505   Earth Resistance Testers
        3 Wire (Analog)  
        ST-1505
        FEATURES
         
         High quality Taut Band movement.
         Capable of measuring earth voltage (Vac).
         The timer operates automatically for about three to five minutes when the "PUSH BUTTON SWITCH" and "TIMER ON BUTTON" are pressed together. This will keep test "ON" for the duration of the timer.
         Battery life indication.
         Battery replacement can be easily made without removing the caring case.
          CAT II 30V.
         Calibration performed with supplied test leads.
