We define measurement tolerances in terms of f.s. (full scale), rdg. (reading) and
dgt. (digit) values, with the following meanings:
f.s. (maximum display value or scale length)
The maximum displayable value or scale length. In this instrument, the maximum
layable value is the range (V/div) times the number of divisions (10) on the verti-
disp
cal axis. Example: For the 1 V/div range, f.s. = 10 V
rdg. (reading or displayed value)
The value currently being measured and indicated on the measuring instrument.
dgt. (resolution)
The smallest displayable unit on a digital measuring instrument, i.e., the input value
that causes the digital display to show a "1" as the least-significant digit.

2.1 Using the Battery Pack (Option)
If commercial power is not available when the AC adapter is connected, the
8870-20 Memory HiCorder can operate from the Model 9780 battery pack, so
when using commercial power, the battery pack serves as a backup supply
during power outages.
Charge the battery pack fully before using it the first time.
Be sure to observe the following precautions. Incorrect handling may result in liquid leaks, h
bursting and other hazards.
• Do not use a battery pack other than the 9780 Battery Pack.

2.3 Connecting Measurement Cables to the Memory HiCorder
Do not connect a cable to the instrument while it is connected
to the object to be measured. Otherwise, an electric shock
accident may occur.
To prevent damage to the instrument and sensor, never connect
or disconnect a sensor while the power is on, or while the sensor
is clamped around a conductor.
Connecting to the logic terminals
T o avoid electric shock and short circuit accidents or damage
to the instrument, pay attention to the following:
• The ground terminal for the
optional logic probe is not
isolated from the Memory
order's ground (chassis
HiC
ground). Therefore, if the
measurement object connect to AC, it should have a
gr
ounded, polarized plug, and be connected to the same
power outlet as the Memory HiCorder’s AC adapter.
If the Memory HiCorder and measurement object are connected to different mains circuits, or if an ungrounded
power c
ferent grounding paths may result in current flo w through a
logic
Memory HiCorder.
• Do not allow the m etal tip of a
between conductors on the measurement object. Never
touch the metal tip of a probe.
• Maximum logic probe input voltages are as follows.
Do not measure if the
