TECPEL CL-327A Manual page 26

Each press of the〔〕/〔〕key increases or decreases the digit. Increasing the digit from 9 or decreasing it
from 0 causes the digit to overflow or underflow, allowing you to set the output value without interruption.
Holding down the〔〕/〔〕key continuously changes the digit in question. And the value won't change if it
is increased or decreased to the Maxim or Minimum value. Pressing the〔ZERO〕key initializes the output set
point to the default value(0).
Step 3: Pressing the〔ON〕key causes the SOURCE indicator on the LCD to change from ''OFF'' to ''ON '' .
The calibrator sources the preset resistance value between the output terminals.
Step 4: To turn off the output, press the〔ON〕key once again. The ''OFF'' appears on the LCD and no signals
sourced between the terminals.
7.6.1 Temperature Monitor Function
The calibrator offers a temperature monitor function, which is convenient for the user to observe the resistance
value sourced between the output terminals.
In RTD source function, LCD shows the resistance value sourced between the output terminals. Pressing the
〔T.DISP〕key once more, LCD shows the present room temperature value in assistance districts part of its.
7.7 Sourcing Frequency
The calibrator can source a constant pulse signal responding to the preset frequency and amplitude.
Step 1: Using the 〔 〕 key, select frequency source function. The LCD shows the default frequency value10
Hz.
Step 2: Using the〔RANG〕key, select a desired frequency range from 100Hz, 1KHz,10kHz,100KHz. The
selected function and the default range source value and unit shall be shown in the LCD.
Step 3: Set the output value digit by digit using each pair of〔〕/〔〕output setting keys.
