Operating Precautions
• The battery pack is a consumable. If the battery capacity remains very low after correct recharging, the useful battery life is at an end.
• When a battery pack that has not been used for a long time is used, charging may end before the battery pack is fully charged. In such a case, repeat charging and discharging a number of time before use. (A battery pack may also be in such a state immediately after purchase.)
• The life of the battery pack (when capacity is 60% or more of initial cap
acity) is approximately 500 charge-discharge cycles. (The life dif-
fers depending on the conditions of use.)
• To prevent battery pack deterioration when the battery will not be used f
or 1 month or longer, remove it and store it in a dry location with an ambient temperature range of between -20 to 30°C. Be sure to dis­charge and charge it every two months. Long-term storage when cap
acity has decreased will make charging impossible and reduce
performance.
• When a battery pack is used, the instrument turns off automatically wh
en the capacity drops. Leaving the instrument in this state for a long time may lead to over discharge so be sure to turn off the power switch on the instrument.
• The charging efficiency of the battery pack deteriorates at high and low te
mperatures.

2.6 Turning the Power On and Off

Right Side
Turn the power switch on ( ).
The power supply icon ap­pears near the bottom right corner of the screen (p. 29).
If the " " indicator is not displayed, the instrument is not being pow­ered from the AC line. In this state, the battery charge will be depleted if measuring for a long time, and measurement may be interrupted. Verify that the AC adapter is securely connected to an AC power source and to the instrument.
Turning Power On
Turn the POWER switch off ( ).
The installed battery pack is charged whenever the AC adapter is plugged into a power outlet, even when the Memory HiCorder is off. In addition, providing there is some remaining battery charge, waveform data and the setting configuration are memo­rized whenever the Memory HiCorder is turned off, so that when the Memory HiCorder is turned back on, the same operating state is displayed.
Verify that the instrument and peripheral devices are correctly connected.
Turning Power Off
The accuracy of the instrument is guaranteed under the condition that the instrument has been warmed up for at least 30 minutes. To ensure accuracy is met, execute zero adjustment approximately 30 min­utes after turning the power on. (p. 49)

About zero position offset of analog input circuits
With this instrument, the zero position may be off­set in a high sensitivity range (10-mV/div range, etc.). Furthermore, the accuracy of the instrument is guaranteed under the condition that the instru­ment has been warmed up for at least 30 minutes. The figure on the right shows the representative characteristics of zero position drift from immedi­ately after the power is turned on. The changes in the zero position are relatively large for 30 minutes after the power is turned on. The existence of these characteristics means that zero adjustment must always be executed before measurements are taken. In particular, when you will take mea­surements for a long time or take high-precision measurements, we recommend 60 minutes of ag­ing before executing zero adjustment.

4.2 Recording Methods (Measurement Functions)
Sampling is performed at high speed so the data is first stored in the internal buf­fer memory. The data stored in the inter­nal buffer memory is displayed on the screen, saved to the storage media, and printed after measurement ends.
Sampling is performed at low speed so the waveform is displayed and the data is saved to the storage media and print­ed* during sampling.
Set the time per division of the horizontal axis (time base).
The fastest time base that can be set is 100 µs/div, which is 1 MS/s when con­verted to sampling speed. (At the magni­fication of x1, the number of data per division is 100.) By changing the setting, you can set the time interval at which to perform sampling in the same way as shown on the right.
Set the time interval to perform sampling.

Retaining Records of Maximum and Minimum Values (Envelope)

The maximum and minimum values within the recording interval are calculated from da ta oversam­pled at maximum sampling speed (1 MS/s), and
corded for each recording interval. Therefore,
re recording without missing the peak of fluctuation will be possible even if a long recording interval is set. (*): Sampling is the acquiring of the data to be saved
internal buffer memory. Oversampling is the acquiring of data at a higher
to the speed than when data is acquired to the internal buffer memory (sampling). Over­sampled data is not saved.

This section describes the minimum re
quired settings for measurement. The input channel mode (instantaneous value/effective value recording) and mea­surement range need to be set before measurement. Change the settings of other setting items as
necessary.
• The frequency range for effective values that can be measure d with the instrument is 30 Hz to 10 kHz. An effective value of a frequency that is out of this range cannot be measured correctly.
• When effective value measurement is perform ed, the response time becomes long if the input voltage is 10% f.s. or less. We recommend configuring the setting so that the input voltage becomes 10% f.s. or more.
• The input signal is displayed as follow s when it exceeds the possible m
easurement range of the set measurement range. Measurement waveform: The data that exceeds the possible mea­surement range is displayed in whit black, and in black when the screen background is white. Measurement values: The data that ment range is indicated as "OVER."
