2.3  Installing the Pens

16

Use only genuine HIOKI P-1200 series felt pens in the instrument. 

2.3 Installing the Pens

Colors: P-1201 (red), P-1202 (green), P1203 (blue)
The letters A through C are appended to the above part numbers depending on the pen type (speed).
(A: standard; B: high-speed; C: low-speed)

See:

"Options" (p. 2)

The P-1201A and P-1202A (PR8112 only) pens that ship with the instrument are the standard “A” type.
Use these pens for general recording work. 
• If you need to record at a low paper feed speed of 120 mm/h or less…

Use “C” low-speed type pens (P-1201C, etc.) for less running.

• If you need to record at a high speed or want the waveform to dry more quickly…

Use “B” high-speed type pens (P-1201B).

• Be sure to stop pen operation before attempting to install or replace pens. Do not apply

excessive force to the pens during recording. Doing so may damage the instrument.

• After use, recap each pen. Leaving the pens uncovered may cause the pen tip to dry out,

making it impossible to record waveforms.

• Never apply any grease or lubricant to the sliding surfaces of the pen holders and the

enclosure. Doing so could cause a malfunction of the pen operation or damage to the
enclosure.

• Once a pen has run out of ink, developed a thick tip, or grown too short, it cannot be used

anymore. Replace it with a new pen. 

• Store unused pens at room temperature, avoiding high temperature and humidity. 
• Dispose of used pens in accordance with local regulations. 
• Lines drawn with A-type and C-type pens are less prone to dry at a low temperature.
• If ink could bleed through a sheet of fanfold recording paper, use a B-type pen or roll-type

recording paper instead.

Installing Pens and Using the Pen Caps

1

Set the pen lever to the 

UP

 (middle)

position. 

The pens will be raised from the recording
paper. 

2

Firmly insert the pen as far as it will go
into the pen holder.

Verify that the pen has been inserted as
far as it will go. 

3

Remove the pen cap and place it on
the pen cap storage pin. 

Pull the cap toward you away from the
pen to remove it.

2

Return the pen caps to the pen tips after
use to keep the pens from drying out. 

For the PR881 (2-pen model), the forward (upper) pen holder is CH1, and the rearward (lower) pen holder is CH2.
