Megohmeter Features - AEMC 5050 User Manual

2.2 MEGOHMETER FEATURES

1. Safety terminals: "+", "G", and "-" and access to the protective fuse.
2. AC power plug (direct operation on AC and battery recharge).
3. Back-lit liquid crystal display.
4. Serial interface.
• Male plug 9 pin for calibration only (Model 5050).
• USB port for connection to a PC (Model 5060).
5. Rotary selector switch with 7 positions:
• OFF - Instrument is off.
• MΩ - 500V - Insulation measurement (to 2TΩ).
• MΩ - 1000V -Insulation measurement (to 4TΩ).
• MΩ - 2500V - Insulation measurement (to 10TΩ).
• MΩ - 5000V - Insulation measurement (to 10TΩ).
• MΩ - 50V-5000V - Insulation measurement with selectable test voltage.
• SET-UP - Set-up of the megohmmeter.
6. START/STOP button.
7. 6 buttons (5050) or 8 buttons (5060), each with a first and second function
The second functions are highlighted in yellow below each button:
• 2 nd
(yellow button)
• R-DAR-PI-DD - Lets you choose the type of measurement to be
performed. Instantaneous Resistance (R), Dielectric Absorption (DAR),
Polarization Index (PI), or Dielectric Discharge (DD).
• R(t) - Shows/hides the interval values of insulation resistance, test voltage
and time-stamping, following a time-controlled test.
• V/TIME - When measuring insulation, pressing this button displays
the time elapsed since the beginning of the measurement, then the
exact voltage generated. When performing resistance or capacitance
measurement, this button has no effect. In MR (memory recall), it displays
the date and time at which the measurement was stored, the exact test
voltage and the OBJ : TEST number.
- Activates or deactivates the "time-controlled" test mode.
•
- Turns the display backlight ON or OFF.
•
• ALARM - Activates or deactivates the alarms programmed in SET-UP.
• - Selects a parameter to be modified.
• SMOOTH - Stops/starts smoothing of displayed values during insulation
testing.
• ▲ - Increases the flashing parameter being displayed. To move about the
list of interval insulation measurements, in the R(t) function.
