Introduction
Safety Precautions
Introduction
This Scanning Thermocouple Thermometer continuously monitors
temperatures at up to 12 locations. It is designed for laboratory or
industrial applications for unattended temperature monitoring. An alarm is
set off when any thermometer exceeds its preset minimum or maximum
temperature. Temperature data is stored within the unit and can be
output to a printer or PC.
Safety Precautions
DANGER:If thermocouples are at a high voltage, this voltage may be
present at other points inside the instrument and outside at
all the connectors.
WARNING: Disconnect or turn off power source before making
connections.
WARNING: Turn power off and completely disconnect instrument.
Disconnect power source, thermocouples, computer, links,
and printer.
WARNING: Other than a lithium battery, there are no user serviceable
parts inside. Replacement of the lithium battery must be
performed per the Maintenance section of this Operating
Manual. Refer servicing to your dealer.

Other Alarms
•OPEN thermocouple: A thermocouple channel that is OPEN (no
thermocouple connected) will cause an OPEN alarm.
OPEN will be displayed instead of a temperature when that
channel is displayed.
Check thermocouple connection, wiring to the thermocouple, or
replace the thermocouple.
If the channel is not used, disable the channel (see How to Enable/
Disable channels, page 30).
•UNDER alarm: If the instrument detects a reading indicating a
temperature below the operating range of the thermocouple type
an UNDER alarm occurs.
UNDER will be displayed instead of a temperature when that
channel is displayed.
•OVER alarm: If the instrument detects a reading indicating a
temperature above the operating range of the thermocouple type
an OVER alarm occurs.
OVER will be displayed instead of a temperature when that
channel is displayed.
•LOG FULL alarm: 4,680 12-Channel records can be stored in
memory. A record is stored in memory manually by pushing
STORE, or automatically according to the log rate setting in the
menu.
During a LOG FULL alarm LOG and FULL alternate in the display.
During a LOG FULL alarm you can:
• RECALL - scroll through the logged readings.
• PRINT - print the logged readings.
To clear (erase) the memory: push CLEAR then push LOG.
•Instrument errors: Various hardware errors can also cause an
alarm such as an A/D error, EEPROM verify error, flash write error,
etc. The entire display will flash the alarm message. See Error
Messages, page 62.
Normal display updates stop until the alarm is acknowledged.
Other updates (scanning, printing, other alarms, logging) continue
without interruption.

How to adjust the print rate
The print rate is the time the instrument waits between printing
temperature scans on the attached printer.
A printer must be attached and turned on. The instrument only sends the
data, there is no alarm or storage of print information if the printer is
disconnected or turned off.
The PRINT button must be pushed and PRINT displayed.
The default setting is 00:20 (20 seconds).
It takes 4 seconds to do one 12 channel scan so a print rate of 00:04 is the
maximum obtainable.
Note: If the print rate is set more often than the scan rate (lower time
setting) the instrument will scan and print at the print rate.

How to adjust the log rate
The log rate is the time the instrument waits between logging temperature
scans in memory.
4,680 12 channel scans can be logged in memory, then LOG FULL is
displayed. When LOG FULL is displayed you can RECALL – scroll through
the logged readings, and you can PRINT – print the entire list of 4,680
logged entries. To clear (erase) memory: push CLEAR, then push LOG.
The default setting is 00:20 (20 seconds).
It takes 4 seconds to do one 12 channel scan so a log rate of 00:04 is the
maximum obtainable. The longest interval that can be set is 1 hour, 60:00.
Examples: At a setting of (00:20) the log is full in 26 hours . At the minimum setting (00:04) the log is full in 5.2 hours. For 8 hours use a setting of
00:09. At the maxim um setting (60:00) the log is full in 4,680 hours (195
days).
Manually pushing STORE adds one scan to the same memory as LOG.

How to do a field calibration
Factory calibration is stored in protected, non-volatile memory. Field
calibration is usually used to reduce probe errors over a specified range.
All field calibration values may be cleared (returning the instrument to
factory calibration) by pushing and holding CLEAR during the power up
display test.
An individual channel's field calibration may be cleared. When CALPT1
is displayed, press and hold CLEAR until CALPT1 CLR is displayed. This
also clears CALPT2 for this same channel. The CAL icon will also go off
for this channel.
There are no restrictions on what values may be entered for field
calibration.
Two calibration points may be entered for each channel. After CALPT1 is
entered the prompt for CALPT2 appears.
If only CALPT1 is entered the offset is affected.
If both CALPT1 and CALPT2 are entered, both slope and offset are
affected.
(See calibrating to the freezing/boiling points of water on page 53, for an
example.)

Note: Service field calibration can only be performed by an authorized

Service calibration performed on 04/09/98 at 13:28:47
Field calibration status as of 04/09/98 14:11:50, scale = C
Calibrate CALPT1 to the freezing point of water (0°C or 32°F) by using
crushed ice made of distilled water. Immerse the probe in a flask
(insulated) filled with crushed ice and topped off with distilled water.
Add crushed ice to keep the flask full of crushed ice and water during
calibration.
Boiling Point
Calibrate CALPT2 to the boiling point of water (100°C or 212°F) by using
distilled water and correcting for altitude and barometric pressure. As a
rule of thumb the boiling point of water decreases 1°C or 1.8°F for every
1000 feet above sea level. Correction for barometric pressure is usually
required only in the case of severe high or low pressure weather conditions.
Note: This method is less accurate than using a dry block calibrator or a
thermocouple calibration furnace. Boiling point calibration is only recommended when this equipment is not available and two point calibration is
required.
