Micro-Ohmmeter Model 5600
AC Power Selection
The Model 5600 may be recharged by 110V or 220VAC (47 to 450Hz).
The instrument includes a 110V supply cord, which provides the
charging voltage for the rechargeable battery. Verify that “110V” appears
on the indicator located below the line cord indicator socket on the front
panel; this will permit recharging with the 110V supply cord.
To change the charging voltage, disassemble the unit as previously
noted. Move the switch on the power supply board to the “220V” position
(see Fig. 3). A 220V supply cord (not supplied) is required for 220V
operation. Be sure to change the indicator on the front panel to the
“220V” position by removing the two screws that secure it and turning the
indicator over.
