Calibration
Calibrate your meter once a year to ensure that it
performs according to its specifications. Contact the
nearest Service Center or refer to the 80 Series Service
Manual for calibration procedures. For replacement parts,
see the parts list at the end of this manual.
To avoid electrical shock, remove the test
leads and any input signals before replacing
the battery or fuses. To prevent damage or
injury, install only quick acting fuses with the
amp/volt ratings shown in Figure 4.
Battery Replacement
The meter is powered by a single 9V battery (NEDA 1604,
6F22, or 006P). Referring to Figure 4, use the following
procedure to replace the battery:
1.
Disconnect test leads from any live source, turn the
rotary switch to OFF, and remove the test leads from
the front terminals.
2.
The case bottom is secured to the case top by three
screws and two internal snaps (at the LCD end).

Warning
Using a Phillips-head screwdriver, remove the three
screws from the case bottom and turn the case over.
3.
Lift the input terminal end of the case top until it
gently unsnaps from the case bottom at the end
nearest the LCD.
4.
Lift the battery from the case bottom, and carefully
disconnect the battery connector leads.
5.
Snap the battery connector leads to the terminals of a
new battery and reinsert the battery into the case
bottom. Dress the battery leads so that they will not
be pinched between the case bottom and case top.
6.
Ensure that the case top rotary switch and circuit
board switch are in the OFF position.
7.
Replace the case top, ensuring that the gasket is
properly seated and the two snaps on the case top (at
the end near the LCD) are engaged. Reinstall the
three screws.
