How to Use
⚫
Loading batteries
(1) Place the Function Switch in Power-Off position.
(2) Take the main unit out of the carrying case and load six
“C” size alkali batteries (LR14) in the
battery compartment located at the back of the unit. Make sure to load them with correct
polarities.
(3) Put the unit back to the carrying case. Place the Function Switch in BATT position and make

Adjustment and confirmation before starting measurement
For proper use of this instrument, make adjustment and confirmation in following procedure
before every measurement.
A
Confirmation of battery capacity
(1) Place the Function Switch in BATT position. Confirm that the pointer is in the blue zone of
the scale plate. When the batteries are new, the pointer will point to the right end (plus side),
which is normal.
Note:
The power lamp will not light during this procedure.
(2) If the pointer is not in the blue zone, replace all the batteries with new ones.
Note:
When replacing the batteries, the Function Switch must be in Power-Off position.
After replacement, place the Function Switch in BATT position and confirm that the
pointer points to the right end (plus side).
B
Zero adjustment of pointer
(1) Place the instrument horizontally.
(2) Confirm that the Function Switch is in Power-Off position.
(3) Confirm that the pointer points the zero on the scale.
(4) If the pointer does not point the zero, set the pointer at the zero by carefully turning the Zero
Adjustment Pivot with a screwdriver either to left or right.
Note:
See the scale plate from straight above.
