Hioki 8847 - Battery Operating Time

Appendix 4 If the Model 9784 DC Power Unit is Installed
A14
Battery Operating Time
(Nominal values at normal room temperature)
Battery used: 12 V, 38 Ah, fully charged
The above times are affected by battery age and state of charge, ambient tem-
perature and other factors.
Even when operating from AC power, some power is consumed from the DC
source if the DC Power Unit is in the standby state (the power switch is on). In
this state, battery operating time is about 5000 hours.
• When using the DC Power Unit, printer specifications change as follows.
1. Maximum paper feed rate is 1 cm/s. (Consequently, real-time printing for
continuous recording length operation is available at timebase settings
slower than 1 s/div.)
2. The [Print Speed] setting has no effect.
• When using the printer, ensure that the input voltage does not drop below 10 V
DC. Otherwise printer malfunction may occur.
1 Verify that the power switch on the
Power Unit is turned off.
2 Connect the positive lead of the con-
nection cable to the positive terminal
on the Power Unit, and the negative
lead to the negative terminal.
3 Connect the positive lead of the con-
nection cable to the positive terminal
of the DC source, and the negative
lead to the negative terminal.
4 Turn the power switch on.

• The Power Unit has no external battery charging function.
• When using batteries, be careful to avoid overdischarging.
• The Power Unit shuts off output if it detects overcurrent or overvoltage.
If this occurs, turn the switch on the Power Unit off for about one minute, and
then back on.
