Page 8: Operation
OPERATION Before taking any measurements, read the Safety Information Section. Always examine the instrument for damage, contamination (excessive dirt, grease, etc.) and defects. Examine the test leads for cracked or frayed insulation. If any abnormal conditions exist do not attempt to make any measurements. - Page 9 LCD Segment Check Press HOLD button while turning the meter on, and all LCD segment will be keep turn on until releasing HOLD button. Hold Feature Pressing the HOLD key to enter the Data Hold mode, the"HOLD" annunciator is displayed. When HOLD mode is selected, the meter held the present readings and stops all further measurements.
- Page 10 PEAK ± Hold Feature Pressing PEAK ± key to enter the PEAK ± hold mode, Push PEAK ± key to cycle through the peak+/ peak- readings. To prevent accidental loss of PEAK ± data, In this mode can only be cancelled by pressing and hold down the PEAK ±...
- Page 11 REL relative Button Pressing REL key to enter the Relative mode and the "D" annunciator is displayed, then store the displayed Reading as a reference value.Pressing REL key again the "D D D D D " annunciator will be blinking, LCD reads reference value. Pressing and holding down the REL key for 1 seconds to exit REL mode.
- Page 12 Voltage Measurements 1. Connect the red test lead to the "VW " jack and the black test lead to the "COM" jack. 2. Set the Function/Range switch to the desired voltage type (AC or DC) and range. If magnitude of voltage is not known, set switch to the highest range and reduce until a satisfactory reading is obtained.
