2.3 Installing the Pens

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, etc.).

• 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.

• 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.

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.

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.

2.4 Connecting the Power Source (Alkaline Batteries or AC Adapter)

You can power the instrument with either mains power or batteries, depending on where you’re

using it. If you use mains power while batteries are installed in the instrument, the AC adapter takes

precedence.

When you are unable to operate the instrument using mains power, you can power it with six LR20

alkaline batteries instead. The batteries will also serve as a backup power source in the event of a

power outage when using mains power.

2.4 Connecting the Power Source (Alkaline

Batteries or AC Adapter)

Installing Alkaline Batteries

 Checking the remaining battery life

You can check how much battery life remains with the Power LED.

Green Indicates ample remaining battery life.

(Also lights up when powering the instrument with the AC adapter.)

Orange Indicates limited remaining battery life. It is recommend to have new batteries ready to use.

Red Indicates low remaining battery life.

It is recommended to replace the batteries in the instrument with new batteries.

 Estimated operating times

• PR8111 (1-pen model): Approx. 50 hours

• PR8112 (2-pen model): Approx. 25 hours

When using the PR8112 (2-pen model) with just one pen, you can set the CH2 POWER switch on the

rear of the instrument to OFF to realize similar operating times as for the PR8111 (1-pen model).(p. 26)

Before installing batteries into the instrument, be sure to read "Using the Batteries" (p. 7).

Required: One Phillips head screwdriver, six LR20 alkaline batteries

1 Turn off the POWER switch.

If the instrument is connected to the AC adapt-

er and cables, disconnect them.

2 Use the screwdriver to remove the screws

holding the battery cover in place on the

back of the instrument and remove the

battery cover.

3 Install six new LR20 alkaline batteries.

4 Reattach the battery cover and tighten it

securely in place with the screws

removed in step (2) above.

The battery cover is held in place by M3-size screws.

To ensure safe operation, affix the battery cover with

screws. Avoid mixing new and old batteries or differ-

ent types of batteries. Note the positive and negative

poles and exercise care not to install the batteries

backwards. Doing so may result in degraded perfor-

mance or cause the batteries to leak.

2.4 Connecting the Power Source (Alkaline Batteries or AC Adapter)

Connect the Model 9418-15 AC Adapter and power cord that came with the instrument and then

connect the power cord to a wall outlet. When the adapter is used along with alkaline dry-cell batter-

ies, the AC adapter takes precedence. If the supply of power from the AC adapter is interrupted, the

instrument will switch over to battery power. When power returns, it will automatically revert to

power from the AC adapter.

You can also use the instrument with DC power source input, for example from an external battery.

The instrument can be powered with a 10 to 27 VDC signal from the AC adapter jack. Hioki can pro-

vide cables for this purpose on a special-order basis. For more information, please contact your

dealer or Hioki representative.

The cable connecting the battery and instrument should not exceed 3 m in length.

Connecting the AC adapter

Before connecting the AC adapter, be sure to read "Using the AC Adapter" (p. 7) and

"Handling the Cords and Cables" (p. 6).

Rated supply voltage is 100 to 240 VAC, and rated sup-

ply frequency is 50 or 60 Hz.

1 Connect the power cord to the inlet socket

on the AC adapter.

2 Connect the output plug of the AC adapter

to the instrument.

3 Plug the power cord into the mains outlet.
