Section 1 General

1.1 DESCRIPTION

The Anderson DTG Digital Temperature Gauge is a fully electronic, battery powered
device designed as an “Alternate Temperature Indicating Device” for use in Retorts.
This device features a dual element design that provides continuous error checking
of the temperature signals. Units are shipped from the factory with a certicate of
calibration against an NIST traceable source. For on-site calibration, from two to ve
user scaling points are available to match an in-house customer supplied reference

standard.

With the above features, this unit meets all requirements as outlined in the Code of
Federal Regulations (CFR) covering the processing of low acid canned foods.

The simple to read LCD display incorporates a “low battery” indicator to signal the

need for replacement of the batteries.

Dual temperature elements feed a continuous comparator circuit. A visual warning
is provided via the LCD display for any deviation beyond .5 deg F from the primary

to the secondary element. In this condition, both the primary and secondary element
readings are shown on the display, and may be compared to a secondary device
such as the recording thermometer installed in the process. This allows the process

to run without the need for an emergency shutdown as in the case of a broken

mercury thermometer.

programming.

5.1 CHANGE OFFSET VALUE

The “Offset Value” function is used to apply a linear offset factor to the device. If your DTG
shows a repeatable discrepancy (less than 1 degree) throughout the test range, this function
may be used to remove the differential.

Example: Reference reads 32.0°F and DTG reads 32.3°F
Reference reads 150.0°F and DTG reads 150.3°F
Reference reads 212.0°F and DTG reads 212.3°F

“Offset Value” of “-0.3°F” programmed will remove discrepancy

CAUTION: Be sure to use only an NIST traceable reference thermometer that is known
accurate, and within it’s specied calibration period.

1. Flip Run switch to the
down position.

2. Press Menu switch up
and release once to go to
Offset screen.

3. Use Value switch to set

Offset from 0.0 to +/-5.0.

4. Flip Run switch to the middle position.

PAGE 9

5.2 CHANGE UNIT OF MEASURE

The DTG may be programmed to read in either Degrees F or Degrees C. When changing

from one mode to another, any “User Calibration” points are converted automatically to their
respective unit of measure – no additional programming is required.

1. Flip Run switch to the
down position.

2. Press Menu switch down
and release once to go to
Unit screen.

3. Use Value switch to

PAGE 10

5.3 CHANGE DAMPENING FACTOR

The “Dampening Factor” is used as a means to slow down the reaction rate of the unit. Under
most circumstances, this value should be set to “0.” If a process has very erratic temperature
shifts, and the display uctuates, introduction of a small dampening factor may smooth display.

1. Flip Run switch to the down
position.

2. Press Menu switch down
and release once to go to
Unit screen.

3. Press Menu switch down
and release once to go to

5.4 CHANGE DECIMAL POSITION

The DTG is capable of displaying to the nearest WHOLE DEGREE, or with the addition of
a decimal point, to the NEAREST TENTH degree. Modifying this parameter requires no

additional programming changes to “User Calibration” points.

Note: When reading in WHOLE DEGREES, the display will ROUND DOWN to the previous
whole number.
Example: Unit programmed to display tenths
Actual process temperature 190.7 degree F
DTG display shows 190.7 degree F
Unit programmed to display WHOLE NUMBERS
Actual process temperature 190.7 degree F
DTG display shows 190 degree F

5.5 USER CALIBRATION

The DTG is provided from the Factory fully calibrated and traceable to an NIST reference. If
the user chooses, from TWO to FIVE custom calibration points may be activated. This function
allows adjustments to be made at specic points that match the process, or to remove slight
discrepancies between factory and eld reference standards.

CAUTION: Prior to performing “User Calibration” point entries, be sure to RESET the “Offset
Value” to “0” if any entry has been made.

Hold the Value switch up

for 5 seconds to capture the
calibration information.

This shows the user the calibration is not being implemented. The values for Point

1 are saved, but they are not used. The user needs to return to the End User
Calibration and add at least one additional calibration point and then save the

calibration.

5.7 RESET ANY POINT

The “Reset Any Point” function will allow a “User Calibration” point to be disabled. Keep in mind
that a minimum of TWO “User Calibration” points must be utilized, so an “Err” condition may be
activated if only two points were in place and one is deleted.

If multiple “User Calibration” points have been implemented, and one of those points is deacti­vated, no additional programming is required. The DTG will properly reference the new “User

Calibration” point sequence.

6.1 BATTERY REPLACEMENT

The DTG is supplied with two thionyl chloride lithium
batteries pre-installed. Under typical usage, six to

twelve months of operation can be realized.

CAUTION

The supplied batteries have a voltage output greater

than a typical alkaline – DO NOT place the supplied

batteries into any other device other than a DTG.

Standard alkaline batteries may be used, but typically
have a shorter life and may be affected by high
temperature; battery leakage may occur.

Replacement TCL batteries may be ordered directly

from Anderson.

A three segment battery indicator allows the operator to monitor battery life of the
DTG, and plan ahead for a battery change. When a low threshold is reached, the
nal indicator bar blinks on and off. Internal circuitry regulates battery voltages to
ensure all factory specications are met, even with a decrease in battery voltage.
When an unacceptable level is reached, the DTG will shut down. Internal ash
memory retains all prior calibration, and only replacement of the batteries is required

to resume operation.

6.2 SELF CHECK - ERROR CONDITION

The Digital Temperature Gauge features continuous error checking between the Primary and Secondary
temperature elements. In the event of a discrepancy greater that 0.5 degree F, the unit will display an error

condition. As illustrated below, the display will alternate between the current primary element temperature, an
error warning message and the secondary element temperature.

By recording the temperature shown for the primary and secondary elements, a comparison against the
RECORDING THERMOMETER may be performed. This action will allow you to determine which element
(Primary or Secondary) has shifted beyond allowable tolerance.

NOTE: If the display has been programmed to indicate WHOLE NUMBERS, the unit will automatically shift to

tenths display while in error condition.
