[5] DESCRIPTION OF FUNCTIONS
5-1 Switches and Adjusters
Function/Range selector
Selecting the desired function or range.
Mechanical zero meter adjuster
Adjusting zero position by turning it with a screwdriver (see the figure at the
bottom on the next page. At this time, the power switch must be kept OFF.
Power switch and power ON indicator lamp
Sliding the switch upward (ON direction) turns on the power and
the power ON indicator lamp blinks, indicating that the unit is
ready to be operated.
Sliding the switch downward (OFF direction) turns off the power
and the power ON indicator lamp goes off.
Be sure to turn off the power switch after use, as the built-in
batteries are consumed.
Electrical zero meter adjuster (ZERO ADJ) : Operates with layer-
built cell (6F22)
Operate this adjuster after the mechanical zero meter adjustment
and turning on the power switch.
• In the measurement of ±DC voltage (±DCV) and ±DC current
(±DCA), turn on the power switch, and then turn this adjuster to adjust
the pointer to the zero position at the center of ± DCV
•
A scales.
• In the measurement of the functions other than the above, turn on the
power switch, and then turn this adjuster to adjust the pointer to the
zero position.
0
Ω
adjuster (0
Ω
ADJ): Operates with model R6P(SUM-3 battery 1.5 V)
Use this for the resistance measurement. Before measurement, turn
on the power switch and short-circuit the test pins of test leads and
turn this adjuster to adjust the pointer to the 0
Ω
position.
5-2 How to Use the Stand
Tilt the stand attached to the rear case as shown in the figure on
