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.
CAUTION: Be sure available power matches instrument power require-
ments.
CAUTION: Protection provided by the unit may be impaired if the unit is
installed and/or operated in a manner inconsistent with
these instructions.

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.
LOG
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

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.)

How to calibrate to water
How to calibrate to water
Ice Point
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.

Factory Default settings
A variety of parameters are user set-able using the MENU.
Your menu settings are retained in memory even when the instrument is
turned off or disconnected from a power source.
When the unit is first turned on, the memory contains the factory default
menu settings. To erase all the menu settings and reset the instrument to
factory default menu settings:
1. Turn off the power using the power switch on the back of the
instrument.
2. Turn power back on, and before the instrument completes the
display check (before the small 12 turns off).
3. Push and hold MIN and MAX.
