CAUTION
No compliance with the Warnings and/or Instructions may damage the apparatus and/or its components or injure the operator.

Use the instrument and the probes only within the ranges specified in this manual and in the probes’ ones.
Do not perform any measurement on materials under voltage. This could damage the instrument.
If during a measurement the read value or sign never changes, please verify if the HOLD function is active.

AFTER USE

When the measurements are completed switch off the instrument.
Remove batteries when the apparatus remains unused for long periods.

GENERAL DESCRIPTION

The instrument can performs the following measurements:

Temperature measurement in °C/°F/°K by means of K, J and T type probes
Maximum, minimum values measurements
Data HOLD
Offset adjustment for compensation of external probes
Backlight
Auto Power OFF

Each function could be selected via the relative key. The selected quantity appears on a high-contrast display with indication of measurement unit and of the active functions. There are also the function keys, for their use please see § 4.2.

PREPARATION FOR USE

INITIAL

The instrument has been checked from every point of view before shipment. Every care has been taken to make sure that the instrument reaches you in perfect conditions. However, it’s advisable to make a rapid check in order to detect eventual damages, which may have occurred in transit. Should this be the case, enter immediately the usual claims with the carrier. Make sure that all the accessories listed in § 7.3 are contained in the package. In case of discrepancies contact the dealer. In case of returning of the tester, please keep to the instructions given in § 8.

POWER SUPPLY

The instrument is supplied by 1x9V alkaline battery type IEC 6F22 included in the package. Battery life: about 200 hours. When battery is low, the symbol ” ” appears on the display. Replace it immediately, following the instructions given in § 6.2.

STORAGE

In order to guarantee the accuracy of the measurements, after a period of storage in extreme environmental condition, wait for the necessary time so that the instrument returns to normal measuring conditions (see § 7.2.1).

FUNCTION KEY DESCRIPTION

ON/OFF key
By pushing ON/OFF key permits to turn on and off the instrument. After turn on, the backlight is active and it automatically disabled after approx. 20s.
UNIT/ key
By pushing UNIT/ key permits the temperature measurement unit selection among the option: “°C” (Celsius), “°F” (Fahrenheit) and “K” (Kelvin). The UNIT/ key is disabled if the function “HOLD” is activated..
The formulas that links Celsius and Fahrenheit degrees are:
T [°F] = T [°C] * 1.8 + 32
so: 0°C are equal to 32°F, 100°C are equal to 212°F
By pushing long (>2s) of UNIT/ key permits to activate/disable the backlight.
JKT key
By pushing JKT key permits to set the type of external probe (K, J or T) to be connected to the instrument. Cyclically the K, J or T settings are displayed.
MAX and MIN key
By pushing MAX or MIN key permits to detect the Maximum or Minimum values of measured temperature. The secondary display shows the symbol linked to the selected function: The symbol “MAX” for maximum value and “MIN” for minimum value. The MAX or MIN values are dynamically updated while the real time value of temperature is displayed on the main display
HOLD/ENTER key
By pushing HOLD/ENTER key the instrument’s measured value is frozen on the display and the symbol “HOLD” appears on it. The HOLD function does not influence the secondary display.
keys
Use the and arrow keys to set the offset values during the calibration operation of the probe fitted in the terminal input of the instrument (see § 4.3.7).
CAL key
The CAL key permits to perform compensation on the temperature measurement due to a possible error of the input probe. Follow the below steps:

By pushing long (>3s) CAL key to enter in the calibration section. The below screen is shown at display:
- Compensation of temperature probe
On the main display the real time value of the temperature is displayed while the measurement offset value is displayed on the secondary display. The default value is “0.0”. Do not modify this default value if any compensation is needed
Push the or arrow keys respectively to increase or decrease the offset value. The maximum set values are: 5°C or 9°F with a 0.1°C / 0.1°F resolution
. By pushing long (>3s) again CAL key to save the settings and quit this mode. The instrument keeps the set value after each shutdown

Disabling Auto Power OFF
The instrument is provided with Auto Power OFF (APO) feature which automatically permits to switch it off after 15 minutes of idleness in order to preserve the internal battery. To disable this feature follows the below steps:

With instrument on, push and keep the HOLD/ENTER key
By pushing long (>1s) the ON/OFF key. The “APO OFF” message is shown at display for a while
- Disable/enable Auto Power OFF
  and the “ “ symbol disappears from display
Repeat the same operation of the point 1 and 2 for enable again the function with “APO ON” message shown at display

Disable/enable Auto Power OFF

or the feature is automatically restored after each shutdown

OPERATING INSTRUCTIONS

TEMPERATURE MEASUREMENT

CAUTION
