  • Page 2 This instruction manual is to provide information that is necessary for you to safely and correctly operate the amplifier units, Omniace II RA1000 series. Please always place this instruction manual together with the amplifier units whenever you use the units, so that you can access and refer to the manual at any time.
  • Page 3 Reprinting or reproduction of this manual, in whole or in part, without permission is prohibited. ● NEC San-ei has made every effort to attain the completeness in contents of this manual. Please feel free to contact your dealer regarding any errors, omissions, questions or suggestions, if you find one.
  • Page 4 WARNING WARNING indication labels of amplifier units ●Input signal connection and permissible common mode input voltages First, confirm that the mainframe is correctly and securely grounded through the protective grounding terminal, before connecting the equipment with a device to be measured. Also, be careful so that the input voltage does not exceed the permissible range of common mode input voltage, when you connect an amplifier unit with the measurement equipment.
  • Page 5 WARNING ●Warning against electric shock and permissible input voltage Do not touch, by any means, metallic portions of the input section, when a high voltage input signal is being applied, to avoid a risk of electric shock. Also, it is very dangerous to apply an input voltage exceeding the range of permissible input voltages for individual amplifier units, since application of such high voltages would cause equipment failures.
  • Page 6  Warranty Application NEC San-ei is making every effort in maintaining a high quality control level for its products from the design to shipping phases. However, in an unlikely event of finding a symptom of failures, you should check the operational status of the equipment, the status of the electric source voltage and the connection status of various cables, before asking NEC San-ei for repair.

  • Page 85 Section 4. Extend setting RA1300 Recording position, pitch of signals, amplitude, recording line thickness and display color of signals can be set. Recording position sets distance from lower edge to low waveform of No.8 signal on the screen (waveform recording). Display color of waveform changes every pressing key of each channel.

  • Page 95 Section 6. Procedures for changing amplifier units Amplifier units can be changed easily, since they have plug-in mounting structure. However, mount or dismount amplifier units, only after you have turned off the power supply switch and disconnected the power supply cable from the mainframe Mounting or dismounting amplifier units while the mainframe is powered on would lead to damages to the mainframe, Omniace II.
