OPERATING INSTRUCTIONS FOR BAT-12 THERMOMETER

1.0 INTRODUCTION

The Physitemp BAT-12 thermometer is a compact, portable, digital thermometer for
use in the lab or in the field. It can be used with any Type T thermocouple sensor and
is available in two versions:

BAT-12

, for battery operation only, uses a 9V alkaline battery.

BAT-12R

, a rechargeable version, is supplied with a 9V Nickel/Metal-Hydride

battery and may be battery operated in the field or AC operated in the lab. A 
heavy duty vinyl carrying case is supplied with both versions.

2.0 INITIAL INSTALLATION

2.1

Remove the packing list (usually found in a transparent envelope on the out-

side of the carton) and unpack the instrument. Check that all items shown on the
packing list are present. Sensor probes ordered with the instrument will be packed in
the same box if small or a separate package if they are longer than 12 inches.

2.2

BAT-12, for battery operation, is supplied ready for use with a 9V alkaline bat-

tery already installed. Shipment will include the carrying case and a male plug for
connection to the analog output.

2.3

BAT-12R for AC and battery operation, is supplied with a 9V Nickel/Metal-

Hydride battery installed. This is shipped with a full charge. To recharge or for AC
use, connect the small phono plug on the AC adaptor to the jack on the rear of the
instrument and plug the charger into a live 115V outlet. 14 hours are required for a
complete recharge. Overcharging will not harm the unit. If requested, an adaptor for
220VAC operation can be supplied. A carrying case and male plug for connection to
the analog output are supplied with
the BAT-12R.

2.4

If Tilt Stand TTS-2 has been

ordered, mount the instrument on the
stand by attaching the ball and socket
mount to the threaded fitting on the
underside of the case.
