Physitemp Instruments BAT-10 - Manual (Page 10)

1.0 INTRODUCTION
1.0 Physitemp laboratory thermometers are compact, digital thermometers for use with type T
thermocouple sensors. The BAT-10 thermometer has two probe inputs for direct temperature read-
ings with a resolution of 0.1°C or 1°C. A third input is used when differential measurements are
made. On the differential range, temperature resolution is 0.01°C.
BAT-10 accepts all Physitemp type T thermocouple probes.
2.0 INITIAL INSTALLATION
2.1 Set the handle/angle bracket to the position most convenient for your application. Pull out
both side bars slightly at the same time. Adjust as necessary then allow to snap back into place.
2.2 BATTERY OPERATED UNITS are supplied with four alkaline “C” cells installed and are
ready for operation.
2.3 RECHARGEABLE UNITS are supplied with fully charged Nicad batteries installed and a
charger kit that is also an AC adaptor.
To recharge and for AC use, connect the power jack on the recharger kit to the AC INPUT socket
on the back of the instrument. Plug the charger into a live outlet. Charger is for use with 110-
115V AC unless otherwise specified on your order. Charger will be labelled for correct voltage.
See Section 9.0 for further information.
3.0 OPERATING INSTRUCTIONS
3.1 The following instructions are printed on a label on the top panel of the BAT-10. They are
reprinted here in case the label is ever defaced. See Sections 4.0 and 5.0 for detailed information.
4.0 TEMPERATURE MEASUREMENT
4.1 Any type T thermocouple (Copper-Constantan) can be used with the BAT-10.
Thermocouple sensors made with “special limits” wire are accurate to 0.5°C in the range 0-50°C.
If better accuracy is required, Physitemp’s microprobes and clinical probes should be used.. These
are manufactured with specially graded wire and are guaranteed accurate to 0.1°C in the range 0-
50°C. See Section 11.0 for more information on temperature measurement with thermocouples.

TEMPERATURE RANGE RESOLUTION
-200°C to +400°C 1°C
-100°C to +199.9°C 0.1°C
Differential -19.99°C to +19.99°C 0.01°C
1. TO MEASURE TEMPERATURE
Insert plug of any type T thermocouple probe into input 1 or 2.
Switch ON. Select range. Select probe input 1 or 2. Ensure DIFF
ZERO button is not depressed. Read temperature.
2. TO MEASURE DIFFERENTIAL TEMPERATURE
Connect probes to input 2 AND 3. Select DIFF range to measure
differential temperature between these probes. Select DIFF ZERO
ADJUST. Use screwdriver to set zero until display reads 0.00.
Release DIFF ZERO to read differential temperature of probe 2
with respect to probe 3. See manual for more detail instructions.
Note: Input 3 is only activated in differential mode. It is not
possible to measure absolute temperature with this input.
3. SPECIAL DISPLAY INDICATIONS
l - Probe is above or below limits of range.
LO BAT - Replace or recharge the batteries
INPUT - Probe, input connector or lead may be faulty.
Replace probe at input selected.
4. BATTERY REPLACEMENT (non-rechargeable units)
USE ONLY ALKALINE BATTERIES
Switch instrument OFF. Unscrew two plastic caps from holders on
back by turning counter-clockwise. Discard old batteries and
replace with fresh “C” cells. Install all four batteries with positive
terminals toward plastic screw caps. Replace caps
5. RECHARGING (rechargeable units only)
Plug AC charger (9V @ 250 mA) into AC INPUT socket on back
of instrumement. Allow 16 hours for complete recharging.
With Ni-Cad batteries installed the unit may be continuously
operated from AC recharger.
