3. Usage

As part of GLP, please familiarize yourself with all reagents used in your application. Read

all product labels and MSDS before working with chemicals.

To ensure proper functioning of all inbuilt safety measures, the instrument may, under no

circumstances, be used or installed in a different way than stated in the manual.

Only use the instrument as instructed to analyze MACHEREY-NAGEL tests. Please do not

open the instrument or make any other unauthorized modifications. The instrument is a

highly sensitive measuring device with high accuracy for the photometric evaluation of

MACHEREY-NAGEL tests. Unauthorized modifications or opening the instrument in an inap-

propriate way can result in maladjustments of the instrument’s optical components, or similar

damage, which in turn can lead to wrong results.

Note: Due to the reasons stated above, MACHEREY-NAGEL declines any responsibility for

the correct functioning of the instrument if it has been opened or used improperly and objects

to any warranty claims made in such a case. MACHEREY-NAGEL’s warranty and liability

obligations as to product(s) or to any party on account thereof shall be void and of no effect

if the product(s) or any part thereof have been subject to unauthorized change, abuse,

misuse, accident or alteration, unauthorized application or installation not in compliance with

the pro- duct(s) specifications as set forth in the product leaflets / instructions hereof

(“unauthorized action”) and such unauthorized.

4. Setup

4.1 Unpacking the instrument

Take the instrument out of the box and check for damage caused during shipment.

4.2 Operation with batteries

The PF-12Plus photometer runs on 4 AA Mignon batteries (included in delivery). Recharge-

able batteries, e.g. 4 NiMH AA 2500 mAh can be used in the instrument and are available as

accessories (REF 919 221). The charger and rechargeable batteries need to be ordered

separately. The battery status is displayed in the upper part of the display after switching on

the device. When connected to an USB adapter, a “U” is displayed besides the battery symbol.

When changing batteries, we recommend to always exchange the entire set. The battery

compartment is at the bottom of the instrument. To change the batteries, the cuvette slot has

to be empty.

1. Turn the instrument around and place it on a soft surface.

2. Unscrew the screws of the battery compartment and take off the lid.

3. Insert the 4 batteries in the respective slots. Make sure polarity of batteries and slots match.

4. Put the lid back on, tighten the screws and turn the instrument around.

4.3 Operation with battery pack

The PF-12Plus can be equipped with an internal battery pack, which can be charged via the

USB port. The charging status of the internal battery pack is displayed in the upper part of

the display in form of a small battery symbol with an “A”. When connected to a USB charger

additionally a “L” is going to be displayed besides the battery symbol, indicating the ongoing

charging process. You can order such a power pack separately and insert it into the instru-

ment. Detailed installation instructions come with the battery pack.
