Omega HH506RA - K, J, T, E, R, S, N Thermometer Manual

INTRODUCTION

The HH506RA is a portable digital thermometer that measures external thermocouples of type K, J, R, S, T, E, and N. The thermocouple types comply with the NIST - ITS 90 standard reference temperature/voltage tables. The thermometer features a dual thermocouple input, an adjustable T/C offset and an RS-232 interface for uploading data to a PC using optional software and cable.

SAFETY INFORMATION

To avoid electrical shock do not use the device when the working voltages exceed 24V AC or DC. To avoid damages to the instrument and/or physical burns, do not make measurements in microwave ovens. Avoid sharp bending of the thermocouple leads to prolong its life, especially near the connector.

To avoid electrical shock, do not use this instrument when working voltages at the measurement surface are over 24V AC or DC.

To avoid damage or burns, do not take temperature measurements in microwave ovens.

Repeated sharp flexing can break the thermocouple leads. To prolong lead life, avoid sharp bends in the leads, especially near the connector.

OPERATING INSTRUCTIONS

Operational Mode

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

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

Shift Mode:
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 lowerrighthand corner of the display panel, the word "Shift" is displayed to indicate shift mode. To switch back to normal mode, press the SHIFT button.

Setup Mode:
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.

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

" " Power Button
The"" button turns the thermometer on or off. When entering data set mode, the power off function is disabled.
"Limits" Button (only main display)
The limits function will alert the user when a measurement exceeds a specified limit. To set the limit values, refer to limits function in the setup mode.
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.
"" button
The backlight function is represented by this button " ". Pressing the button will turn the backlight on or off in the LCD.
"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.
"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 SECOND 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.

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.
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.

"T1/T2" button (MAIN display)
