Maintenance – Calibration
Replacing the Batteries
Attention!
!
Disconnect the instrument from the measuring circuit before
opening the battery compartment lid in order to replace the
batteries.
➭ Set the instrument face down onto the working surface.
➭ Turn the slotted screw on the lid with the battery symbols
counterclockwise.
➭ Lift off the lid and remove the batteries from the battery
compartment.
➭ Insert two new 1.5 V mignon batteries into the battery
compartment, making sure that the plus and minus poles
match up with the provided polarity symbols.
➭ When replacing the battery compartment lid, insert the side
with the guide hooks first.
Tighten the screw by turning it clockwise.
➭ Please dispose of depleted batteries in accordance with
environmental protection regulations!
9.3 Fuse (METRAHIT AM XTRA / O

, METRAHIT AM TECH, METRAHIT
AM PRO and SECULIFEHIT

only)
Testing the Fuse
The fuse is tested automatically:
• When the instrument is switched on with the rotary switch in
the A position
• When the instrument is already on and the rotary switch is
turned to the A position
• In the active current measuring range when voltage is applied
If the fuse is blown or has not been inserted, “FuSE” appears at
the digital display. The fuse interrupts the current measuring
ranges. All other measuring ranges remain functional.
Replacing the Fuse
If a fuse should blow, eliminate the cause of overload before
placing the instrument back into service!
Attention!
!
Disconnect the instrument from the measuring circuit before
opening the fuse cover in order to replace the fuse!
➭ Set the instrument face down onto the working surface.
➭ Turn the slotted screw on the cover with the fuse symbol
counterclockwise.
➭ Lift off the cover and pry the fuse out using the flat side of the
fuse cover.
➭ Insert a new fuse. Make sure that the fuse is centered, i.e.
between the tabs at the sides.
➭ When replacing the fuse cover, insert the side with the guide
hooks first.
Tighten the screw by turning it clockwise.
➭ Dispose of the blown fuse with the trash.
