Page 5: Precautions
3. PRECAUTIONS Page 4 The calibrator should be used in an environment according to table 3.2 and where apparatus will be handled carefully. The calibrator should not be used near aggressive gases and strong magnetic and electric fields. Operation is allowable according to IEC359 for instruments group 1. It can be used in temperatures from +5 to +40 deg C and stored/transported at temperatures from -25 to +70 deg C. -

Page 5 4. OPERATION “power” Supply switch, connects the input power to the calibrator “output voltage” Output voltage terminals: high potential “HI” and low potential “LO”. There is a pushbutton and the indicator for standby/operate function next to the terminals. Indicator flashing is “standby” mode and the output voltage is disconnected. - Page 7 Page 6 “phase” Phase angle between current and voltage signals is set up by the control knob. Pressing the pushbutton below the display selects the range of phase. When the indicator “L” light is on, the range is 0 to +90 and when the indicator “C”...
