CHECK AND MAINTENANCE
Maintenance andcheck items

Procedures

Replacement of ink
tank

The recording ink consumption more or less differs according to working conditions.
It lasts about one month in continuous recording.
When the ink has run short, replace the ink tank with a new one, referring to the loading methodof recording ink on pages 14 and 15.

Cleaning of pen tip

Since ink becomes dry, it is possible that the pen tip
is clogged with ink during a long-time interruptionof recording.
When the pen tip has been clogged, remove thepen body by turning the pen tip counterclockwise,
immerse the pen tip into hot water, and clean itwith the attached cleaning wire.

Replacement of pen
tip

If the recording line becomes obscure due to the wear of the pen tip, replace the pen tip witha new one.

Replacement ofchart paper

The chart paper can be used for about 1 month when
the instrument is continuously operated at the chart
paper speed of 25mm/h.
When the chart paper comes to an end, the end markappears on the right end of the paper.
Replace the chart paper with spare paper, referring to
the “loading method of chart paper” on page 12.

the scale plate and preamplifier unit.
When the scale plate, preamplifier unit and/or reference
junction temperature compensating element have been
replaced due to a scale change or a trouble, perform zeroadjustment and span adjustment without fail, referringto the scale test and calibration on pages 21 and 22.
If the preamplifier unit or reference junction temperaturecompensating element was replaced in the case of athermocouple input, apply an input corresponding to theminimum scale as specified in the scale test on page 21,
and adjust the CJ adjusting trimmer at the front lower partof the servo amplifier unit by turning it under thedetached condition of the front panel, so that the indication meets the minimum scale of the scale plate. Thencalibrate scale.
SCALE CHANGE
1 For DC voltage and thermocouple input, the scale
can optionally be changed, irrespective of the types of
input and scale range.
Be careful with the following items.
• When changing from the DC voltage input to the thermocouple input, mount the reference junction temperaturecompensating element, in principle.
• When changing from the thermocouple input to the DC
voltage input, remove the reference junction temperaturecompensating element.
• A semiconductor element is employed as the reference
junction temperature compensating element, and it is
not necessary to replace this element according to thetypes of thermocouple.
2 For RTD input, the scale can optionally be changed,
irrespective of the types of inputs and scale range.
3 The scale cannot be changed from the DC voltage
input or thermocouple input to RTD input, or from RTD
