User manual - METER SRT-77-XA Explanation of symbols used in the manual: - This symbol denotes especially important guidelines concerning the installation and operation of the device. Not complying with the guidelines denoted by this symbol may cause an accident, damage or equipment destruction. -
Page 4: General Characteristics
2. GENERAL CHARACTERISTICS The SRT-77-XA meter is equipped with thermocouple input (K, S, J, T, N, R, B, E). The measurement range depends on connected thermocouple type. Measurement is linearised by the polynomial characteristics referred to particular thermocouples and temperature of cold ends is compenssated automatically. - Page 5 User manual - METER SRT-77-XA Measurement range -200˚C ÷ +1370˚C -50˚C ÷ +1768˚C -210˚C ÷ +1200˚C -200˚C ÷ + 400˚C -200˚C ÷ +1300˚C -50˚C ÷ +1768˚C +250˚C ÷ +1820˚C -200˚C ÷ +1000˚C Voltage: -10mV ÷ 90mV Measurement accuracy ± 0,1% @ 25°C; ± one digit Accuracy of cold ends temperature ±...

User manual - METER SRT-77-XA placed in ”HOLd” menu (see description of ”HOLd” menu). The detection of the peak can be done if the measured signal raises and drops of value at least equal to parameter ”PEA”. Detected peaks are displayed during the time defined by parameter ”timE” . If a new peak will be detected while one is displayed, this new peak will be displayed and display time counter will be cleared (Figure 6.1). - Page 16 User manual - METER SRT-77-XA state of relay/LED ”SEtP” parameter zone B zone A measure ”HYSt” parameter Figure 6.2.
