QUICK REFERENCE
On
Turns unit on.
Off
Turns unit off.
Data Hold
“Freezes” the display at the current temperature reading.
Memory Record
Activates the Record mode to enable the minimum and maximum
temperature readings to be recorded and stored for recall.
Memory Recall
Displays the stored minimum and maximum temperature readings
while in Record mode.
°F/°C
Permits switching between Fahrenheit and Celsius temperature
scales.
Function
Permits viewing both temperature channel readings and the
differential temperature reading.
1.0°/0.1°
Switches between two temperature resolutions—1.0° and 0.1°.
TEMPERATURE MEASUREMENT
Single Probe measurement
1.
Press ON button to power unit.
2.
Determine temperature scale (°F or °C) by pressing the °F/°C button.
3.
Determine temperature resolution (0.1° or 1.0°) by pressing the 1°/0.1° button.
4.
Insert temperature probe into T1 socket. It may be necessary to press the
FUNCTION button until “T1” is displayed, indicating the unit is sampling from the
probe in the T1 socket.
Note:
The cable and connectors are keyed, don NOT insert cable incorrectly and force
it.
Dual probe and differential measurement
1.
Press ON button to power unit.
2.
Determine temperature scale (°F or °C) by pressing the °F/°C button.
3.
Determine temperature resolution (0.1° or 1.0°) by pressing the 1°/0.1° button.
4.
Insert temperature probe into T1 socket and another temperature probe into T2
socket.
Note:
The cables and connectors are keyed, do NOT insert the cables incorrectly and
force them.
5.
Press the FUNCTION button to alternate between viewing temperature readings
from probe T1, probe T2, and the differential temperature. The FUNCTION
button alternates between the following settings:
When “T1” is displayed, the upper display indicates temperature reading from T1
probe. The T2 probe temperature reading appears on lower display.
When “T2” is displayed, the upper display indicates temperature reading from T2
probe. The T1 probe temperature reading appears on lower display.
When “T1 - T2” is displayed, the upper display indicates differential temperature
of T1 and T2 probes. The T1 probe temperature reading appears on lower
display.
DATA HOLD FUNCTION
1.
To “freeze” the display at the current temperature reading(s), press the DATA
HOLD button (“D.H” will appear along the top of the display).
Note:
While in the Hold mode, pressing the °C/°F, FUNCTION, 1°/0.1°, MEMORY
RECORD, or MEMORY RECALL button will have no affect and will not change the
“frozen” display.
2.
Push the DATA HOLD button a second time to return to normal temperature
sampling (“D.H will no longer appear on the display).
MEMORY RECORD
Press MEMORY RECORD button to activate the Record mode. Once the Record
mode, the unit will begin recording minimum and maximum temperature readings
achieved for the probe indicated on the main display (“T1” or “T2”) (“REC” will appear
along the bottom of the display).
Warning:
The Automatic Shutoff feature is disabled while in Record mode so that
long-term monitoring may be performed.
MEMORY RECALL
1.
While in the Record mode, press the MEMORY RECALL button to recall the
minimum and maximum temperature recordings for the probe appearing on the
upper display (“T1” or “T2”).
2.
The maximum temperature recording appears on the first press of the MEMORY
RECALL button (“Max”) and the minimum temperature recording appears on the
second press (“Min”). A third press of the MEMORY RECALL button returns the
display to the current temperature reading.
3.
Exit the Record mode by pressing the MEMORY RECORD button.
Warning:
The minimum and maximum temperature recordings are automatically
cleared once the Record mode has been exited.
AUTOMATIC SHUTOFF
After 10 minutes, if no button has been pressed, the unit will automatically shut off to
preserve battery life. The automatic shutoff can be overridden by entering the Record
mode (see “Memory Record” section).
RS-232 PC INTERFACE
The unit features an RS-232 output via 3-pole 3.5 mm plug. The output is a 16-digit
data stream that may be utilized for user-specific applications.
Available as an accessory is an RS-232 lead with a 3-pole 3.5 mm jack on one end
(plugs into unit) and a 9-pin female D-Subminiature connector on the other end (plugs
into computer COM port). It is required to link the instrument with a PC.
(Pin 2 = Center Pin, Pin 5 = Ground/Shield)
The 16-digit data stream will appear in the following format: D15, D14, D13, D12, D11,
D10, D9, D8, D7, D6, D5, D4, D3, D2, D1, D0.
Each digit indicates a particular status as shown below:
D0 = End word
D1 to D4 = Upper display reading (D1 = LSD, D4 =MSD)
D5 to D8 = Lower display reading (D5 = LSD, D8 =MSD)
D9 = Decimal point (DP) for upper display (0 = No DP, 1 = 1 DP,2 = 2 DP, 3 = 3 DP)
D11 and D12 = Annunciator for upper display (00 = No symbol, 01 = °C, 02 = °F, 03 =
%, 04 = %RH, 05 = pH, 06 = %O
2
, 07 = mg/l, 08 = m/s, 09 = knots, 10 = km/h, 11 =
ft/min, 12 = mile/h, 13 = µS, 14 = mS, 15 = Lux, 16 = ft-cd, 17 = dB, 18 = mV)
D13 = Annunciator for lower display (0 = No symbol, 1 = °C, 2 = °F)
D14 = Polarity (±) for the display (0 = Upper and lower display are “+”; 1 = Upper “-”,
lower “+”; 2 = Upper “+”, lower “-”; 3 - Both upper and lower are “-”)
D15 = Start word
DISPLAY MESSAGES
An “LBT” message indicates that the battery is low and needs replacement (see
“Battery Replacement” section)
A “---” message indicates that the reading is outside the range of the unit.
