6 Replacing of Batteries or Fuse

Prior to opening the unit in any case remove the test leads from
the measuring points of the circuit to avoid any danger of an
electric stroke.
Never operate the unit in opened condition.
a. If in the lowest ohm range "X 1" during the 0 Ω calibration the
pointer cannot be set to position "0 Ω" any more, both 1.5 V bat-
teries (AA size) must be replaced.
The model MT-300 is additionally supplied with a 9 V battery.
This must be replaced if the 0 Ω calibration of the largest ohm
range "X 10K" is not possible any more.
b. If no measurement is possible at all, the fuse should be
checked and, if necessary, be replaced by one of the same type
(quick acting, 0.5 A). A replacement fuse is available:
with MT-200 at the inside of the lower housing shell
with MT-300 next to the 9 V battery
For the replacement screw off the lower housing shell. While in-
serting the new battery watch the correct polarity: insert the bat-
teries with the positive and negative poles as printed in the unit.
After the replacement firmly screw the housing shell. Only then
take the instrument into operation again.
