OPERATING INSTRUCTIONS

OperationalMode

There are three operation modes–Normal, Shift, and Setup Mode.

NormalMode:

This is the default mode; the operating functions for the normal mode are printed on the top of each button in white.

ShiftMode:

The operating functions for the shift mode are printed in yellow on the buttons. While in the normal mode, push the SHIFT button to switch to shift mode. At the lower- righthand corner of the display panel, the word “Shift” is displayed to indicate shift mode. To switch back to normal mode, press the SHIFT button.

Press the [Limits] button to activate the limits function; the word “LIMIT” should be displayed on the LCD.

When the value of the main display exceeds the Hi limit, the word “Hi” will be displayed and the thermometer will beep in an interval frequency. If the value of the main display is lower then the Lo limit, the word “Lo” will be displayed and the thermometer will beep in a continuous frequency. In Limits function, on K or J Type, and with the scale of temperature at °F, the reading counts should be times 10. (ex: 2100°F means 21000 counts)

To exit the Limits function, press the [Limits] button.

(3)“” button

The backlight function is represented by this button “ ”. Pressing the button will turn the backlight on or off in the LCD.

(4)“SAVE/READ”button

The Read Data function works in conjunction with the Save function in the Shift mode, it is used for reading saved data. The Save function can be activated in Shift mode. Press the SAVE/READ button to activate the Read Data function; the word “READ” should be displayed on the LCD. To navigate around the Saved Data table, press the overlay “SECOND” button until the “#” sign is displayed on the second display panel. The location of the read pointer within the Saved Data table will be displayed. The arrow buttons on the overlay are used for scrolling through the saved data. Pressing the smaller arrow “” or “” retrieves the next saved data. Pressing the larger arrow “” or “” will retrieve the next ten saved data. Pressing the overlay “ESC” button deactivates the read data function.

(7) HOLD mode (only main display)

When HOLD mode is selected, the thermometer holds the present readings and stops all further measurements. To activate the data hold mode, press the HOLD button, and “HOLD” is displayed on the LCD. Pressing the HOLD button again cancels the function, and the instrument will automatically resume measurements.

(8) MIN/MAX with time record mode (only main display)

The MIN/MAX function records the highest and lowest value recorded, and it calculates the average reading, and the differences of MAX to MIN. Press MIN/MAX button to enter the MIN/MAX recording mode. The beeper emits a tone when a new minimum or maximum measurement is recorded. Press the MIN/MAX button again to rotate through the current readings:

MAX: The highest measurement recorded.

MIN: The lowest measurement recorded.

MAX-MIN: The difference of the highest and the lowest measurement.

AVG: The average values of the measurements. This mode works in conjunction with the hold function, pressing the HOLD button will stop the recording and measurements (Previously recorded readings are not erased). Press HOLD button again to resume recording and measurements. To prevent accidental loss of MIN, MAX and AVG data, the MIN/MAX function can only be cancelled by pressing and holding down the MIN MAX key for more than 2 seconds. The Automatic Power Off function, and the power, C/F, REL, SET, Hi/Lo Limits, TYPE, T1/T2 buttons are also disabled.

SHIFTMODE

The following functions can only be used in the shift mode.

(2)“C/F”button

Press the C/F button to select the temperature scale, readings can be displayed in Celsius (C) or Fahrenheit

(F). When the thermometer is turned on, it is set to the temperature scale that was last in use.

(4)“SAVE”button

The save function stores the T1, T2 data in nonvolatile memory. Press the SAVE button to save the current data. The word SAVE is displayed to indicate the data are saved. The build in memory can store up to 128 data. The data can be read using the read function in the normal mode.

(5)“LOG”button

The data log function continuously records the data according to a specified time interval. The time interval can be set using the interval time setup function [INVT] in the setup mode. Press the LOG button to activate the log function; the indicator “LOG” and “MEM” will be dis- played on the LCD. There are 16 groups that are used for storing the log data, and each group uses 64 data slots. If the current log session exceeds 64 data, the log function will automatically use the next group to store the following data. A maximum of 1024 data can be saved in one log session. Press the LOG button again to exit the data log function.

(6)“CLR?”button

The CLR function clears all the saved and logged data in memory. When the CLR button is pressed, indicator

SetupMode:

The operating functions for the setup mode are printed in between two bracket signs “[ ]“ on each button. Press the SET[ ] button in normal mode to switch to setup mode, the indicator “SET” is shown on the left side of the display panel. To switch back to normal mode, press the SET[ ] button.

NormalMode:

The following functions can only be used in the normal mode.

(1) “ I ” Power Button

The“ I ” button turns the thermometer on or off. When entering data set mode, the power off function is disabled.

(2)“Limits”Button(onlymaindisplay)

The limits function will alert the user when a measure- ment exceeds a specified limit. To set the limit values, refer to limits function in the setup mode.

(5)“LOG/READ”button

The Log/Read function works in conjunction with the log function, it is used for reading the log data. The log function can be activated in the shift mode. Press the LOG/READ button to activate the read log function; the word “READ” should be displayed on the LCD. Press the overlay SEC- OND button to rotate through following display menus: T1, T2, GRP, and #.

T1 and T2: Displays the T1 or T2 saved value.

GRP: Displays the current group number.

#: Displays the current location of the read pointer within a selected group. The arrow buttons on the overlay are used for scrolling through the data and groups. Press the smaller arrows “”or “ ” to retrieve the next log data or group. Press the larger arrows “ ” or “” to retrieve the next ten log data or groups. To navigate around the log data and groups, press the overlay SECOND button till GRP appears in the second display panel, and then select the group using the arrows, then press the SECOND button again till the “#” sign is displayed. The location of the read pointer in the selected group will be displayed, and then use the arrows to scroll through the data. Pressing the overlay “ESC” button deactivates the read data function.

(10)“T1/T2”button(MAINdisplay)

The input selection button [T1/T2] selects the input for the main display panel, T1 thermocouple or T2 thermocouple. Press the T1/T2 button to switch between the two inputs. When meter is turned on, it is set to the display that was last in use.

The input selection button [T1/T2] selects the system time and date, or the differential between the two thermo- couples (T1-T2) for the third display panel. Press the T1/ T2 button to switch the display options. When meter is turned on, it is set to the display that was last in use.

“MEM” is displayed and the “CLR” word on upper-right of LCD will blink. Pressing “ENTER” button printed on the overlay in white word to clear all saved and logged data or “ESC” button to exit this function.

(7)“REL”button(onlymaindisplay)

The relative value function can be used for comparing the saved reference value with other measurements. Press the “REL” button to store the current measurement as the reference value, and the “REL” should be displayed on the right part of the LCD. The next measurement will display the relative value compared to the reference value.

Press “REL” button again to clear the reference value and deactivate the relative value measurement function.

(8)“[APO]”button

Press the [APO] button to trigger “Auto power off“ function on or off. In this function, the indicator “APO” is shown at the upper lefthand panel of the LCD. When APO (Auto power off) is enabled, it will automatically turn the thermometer off if the key switch is inactivated according to to the set time (the default time for APO is 5 minutes).
