b. Fuse Replacement
Before fuse replacement, disconnect all test leads and/or ant connectors from any circuit
under test. To avoid damage to the instrument, replace the fuse only with specified ratings.
• Set the rotary switch to the OFF position.
• Disconnect all test leads and/or any connectors from the terminals.
• Open the battery compartment using an appropriate screwdriver.
• Remove the fuse by sliding it out of its bracket.
• Install a replacement fuse (F 500mA/250V, Ø 5 x 20mm).
• Close the battery compartment.
c. Battery Replacement
To avoid false readings, which could lead to possible electric shocks or personal injury,
replace the battery as soon as the battery indicator
disconnect all test leads and/or ant connectors from any circuit under test.
• Set the rotary switch to the OFF position.
• Disconnect all test leads and/or any connectors from the terminals.
• Open the battery compartment using an appropriate screwdriver.
• Remove the battery.
• Install a replacement battery (6F22).
• Close the battery compartment.
