Dual channel thermometer for thermocouples J,K,S Instruction manual >

Technical parameters: Parameters of measurement (both channels): Instrument is designed for measurement of temperature from two thermocouples of types J, K, S with the possibility to display the temperature difference between channels. Measured values are displayed on a dual line LCD display. Instrument compares measured values of temperature with two adjustable levels for each measured channel. Breaking the level is indicated by blinking the proper value on display and by audio indication (switchable). Instrument is equipped with minimum and maximum memory and Hold function. Minimum and...

small current. If accumulator is totally discharged, its full charging in instrument takes approximately 100 hours. Instrument with accumulator is not recommended for permanent operation without ac/dc adapter plugged. Accumulator works only as a standby source in case of power mains failure. Switching ON and OFF the instrument Connect one or two temperature probes to the connectors before switching ON the instrument. Channel 1 connector is on the left and channel 2 is on the right. Switch ON the instrument by pressing ON/OFF key. After switching ON the instrument all symbols on the LCD are...

Press HOLD key in the default mode (displaying of actual measured value) to store actual measured values to internal memory (indicated by short beep). Anytime it is possible to display stored values from MENU (see below). Each pressing of the HOLD key in the default mode causes values stored in HOLD memory are replaced with actual ones. Switched ON instrument permanently updates minimum and maximum memory of each measured values. Press MIN key (resp. MAX key) in the default mode to display minimum (resp. maximum) reading. These minimum and maximum readings are indicated by MIN (MAX) symbols...

Battery voltage of partially loaded battery is displayed. This value illustrates battery condition. Temperature of thermocouple cold junction is indicated. Temperature is being sensed at the location of probe connector. This temperature is used for automatic compensation of thermocouple cold junction temperature. Type of actual selected thermocouple is indicated - symbols J or nicr (K thermocouple) or S . Press ENTER key to enter the thermocouple selection mode (procedure is described below). If the selection is not correct. temperature readings are incorrect. Display refresh mode is...

To set alarms press MENU key, select ALAR from menu items and confirm by pressing ENTER key. Reading ALLO indicates adjusted lower alarm limit. Set the desired value by means of the arrow keys. Press and hold the arrow key UP to make value increase fast. Press and hold the arrow key DOWN to make value decrease fast. Release the arrow key and press ENTER to confirm new limit. Reading ALHI indicates adjusted upper limit of the same alarm. Set the desired value in the same way as in above lower limit. If needed it is possible to get back to lower limit setting of the same alarm by pressing...

Commeter instruments passed the following electromagnetic compatibility (EMC) tests: Battery replacement radiation: EN 55022 class B immunity: EN 61000-4-2 (levels 4/8 kV, class A) EN 61000-4-3 (intensity of electromagnetic field 3 V/m, class B) EN 61000-4-4 (levels 1/0,5 kV, class A) EN 61000-4-6 (intensity of electromagnetic field 3 V/m, class B) EN 61000-4-11 (class A) EN 61000-4-5 (class A) Low battery voltage is indicated on the display with blinking reading "BAT". It is necessary to replace it with new one as soon as possible. Battery is located under small cover on the instrument...
