Simpson 260 - Operating Instructions: General; Check Zero Setting; Observe Caution; Operating Instructions: Specific

OPERATING INSTRUCTIONS, GENERAL,
CHECK ZERO SETTING. Before making measurements,
observe whether the meter pointer rests on the
zero mark, with the tester in the position in
which you intend to use it. (Тї is good instru-
ment practice to lay the tester on its back,
scale horizontal, to avoid the danger of tipping
it over.) If necessary, set the pointer to the
center of the zero scale division, using the
slotted button in the lower center of the meter
cover. This button rotates freely through: 360°.
OBSERVE CAUTION. For your personal protection,
turn off power to the circuit under test before
connecting your multimeter. For the protection
of your instrument, check jack connections and
settings of range and function switches before
restoring power. Switch off again before dis-
connecting leads.
