. PREPARATIONS FOR MEASUREMENT 5-1 Checking Battery Voltage Set the Range Selector Switch to any position other than the OFF position. If the marks on the display is clearly visible without "BATT" mark showing, battery voltage is OK. If the display blanks or "BATT" is indicated, replace the batteries according to section 8: Battery Replacement.
-1 Leakage Current Measurement (1)Set the Range Selector Switch to the desired position. Current to measure should be within the selected measuring range. (2)Measuring out of balance leakage current (See Fig.1): Clamp onto all conductors except a grounded wire. Measured current value is shown on the display. (3)Measuring earth leakage current (See Fig.2): Clamp onto a grounded wire.Measured current value is shown on the display.

7. OTHER FUNCTIONS 7-1 Sleep Function This is a function to prevent the instrument from being left powered on in order to conserve battery life. The instrument automatically enters the Sleep (powered-down) Mode about 10 minutes after the last switch operation. To exit the Sleep Mode, press the Data Hold or Frequency Selector Button or turn the Range Selector Switch to OFF, then to any other position.
. OPTIONAL ACCESSORIES Model 8004 and 8008 (Multi-Tran) These models help Model 2434 to measure current greater than 1000A or to make measurement on a large bus-bar or conductor. (1)Set the Range Selector Switch to "100A". (2)As shown, open the jaws and close them over the pickup coil of Model 8004 or Model 8008. (3)Clamp on a conductor with Model 8004 or Model 8008. (4)Take the reading and multiply it by 10.
