3. Notes to users

3.1. Notice for proper measurement
It is recommended to allow about 15 minutes after power on as warm up time before starting measurement. Traces
may drift a little just after power on. When measuring a signal with high accuracy trace declination, you can correct the
trace position using the automatic calibration function. Before starting up this function, allow enough warm-up time.
The calibration is classified into software calibration for resorting to the automatic calibration function in the menu, and
hardware calibration for optimizing the internal circuitry in a wide range.
1. The software calibration is recommended when the ambient temperature has excessively changed (5 ) or when
1000 operating hours or 6 months has been attained. If the trace is displayed excessively or when it is desired to
optimize the measurement, execute it referring to the automatic calibration. Before calibration, disconnect all inputs
for accurate adjustment.
2. The hardware calibration is necessary to keep the instrument to a stable operation status. It is recommended to
adjust the instrument every 2,000 operating hours or every year.
SOFTWARE CALIBRATION FOR OPTIMUM MEASUREMENT
The changes in measurement accuracy due to use environments (temperature, humidity, etc) can be optimally
corrected automatically by activating the calibration. It is recommended to perform calibration when any of the
following cases applies.
- Before a customer starts to use this instrument first
- When an ambient temperature changes more than 5, compared with that at the time of the previous calibration.
- Every 6 months or 1000 operating hours
- Optimization of measurement accuracy is required
3.2. WHEN CONNECTING PERIPHERAL DEVICES
When connecting a printer and a personal computer to the oscilloscope, be sure that the oscilloscope, the printer and
the personal computer are all off, and then connect them. Pay attention to the direction of the cables and the ports of
the peripheral devices. Before operation, be sure to carry out the setting necessary for the printer and the personal
computer. (For the setting of the printer and the personal computer, refer to the operation manual for each) If you
operate the printer and the personal computer which are improperly set, abnormal operation will occur. In this case,
turn off the instrument, the printer and the personal computer at once, and set them properly again and operate them.
Note:
Before using peripheral devices, Interface card should be installed in this instrument.
