9.1 Compact Charger Type PGDC4
Compact Charger & Transformer
This is the standard charger that is supplied with each new instrument unless otherwise requested.
The Compact Charger is designed to optimize the charging of the battery and minimise the charge time by continuously electronically
monitoring the state of charge. When used with these chargers the instrument must be switched off during the charge period.
Note that these chargers only make use of two of the three charging pins on the rear of the instrument.
9.2 5-Way Charger Type PGDC5
This charger operates in the same manner as the compact charger but is directly powered from the mains supply via an IEC mains
connector.
9.3 Vehicle-Mounted Charger Type PGDC3
The PGDC3 charger is specially designed for use in vehicles where the charging power is derived from the vehicle battery. The
charger is designed to optimize the charging of the battery and minimize the charge time by continuously electronically monitoring the
state of charge.
9.4 Charger Type PGDC2, PGDC2/I
The PGDC2 single instrument ‘Smart’ charger and PGDC2/I single instrument ‘Smart’ charger/interface unit are designed to optimize
the charging of the battery and minimize the charge time by continuously electronically monitoring the state of charge. When used with
these chargers the instrument must be switched off during the charge period.
Note that these chargers only make use of two of the three charging pins on the rear of the instrument.
9.5 Battery Module Charging
Rechargeable battery modules may be charged separately from the PGD2 instrument using a Battery Module Charger Adaptor Plate
Type PGD/ADT.
This provides a flexible and economical method of separately charging the PGD2 battery module.
The plate can only be used with the single instrument mains powered ‘Smart’ charger Model PGDC2.
The plate locates into the lower section of the charger with the charger pins passing through the cut-out of the adaptor plate. The
battery module is first removed from the instrument as shown in Section 10 and then placed into the adaptor and is charged in the
same manner as for a complete instrument as described in Section 9.4.
10 B ATTERY R EPLACEMENT
To replace the rechargeable battery module, remove the instrument from its protective rubber boot. In order to remove the rubber
boot, first remove the straps (if fitted). This is performed by depressing the clips on both sides of the instrument. With the straps
removed, ensure that the rubber boot is not snagged on the three charging pins at the rear of the instrument. Hold the instrument in
the palms of the hand with your thumbs on the vacant strap clips. Place the base of the instrument across the edge of a firm surface
e.g., a table or workbench. Push down on the vacant strap clips firmly and the PGD2 will release from the tapered rubber boot. The
boot can then be pulled off the instrument thus avoiding the need to ‘peel’ back the boot and potentially damage it. Undo the lower
three ‘Allen’ screws using the tool supplied (2mm A/F) – see Figure 3 in section 5. It is then possible to pull out the complete battery
module.
Note that the screws are retained in the cover by small ‘O’ rings over the screw threads.
