Measuring with the Built-in Multimeter
The Calibrator is equipped with an ac/dc voltage, current, current leakage, and time
interval meter. The meter has three selectable modes as well as a help guide:
• Multimeter: The meter will measure up to 1100 volts rms and up to 30 amps rms
simultaneously. This makes it possible to measure power consumption and line
current simultaneously when calibrating Appliance testers.
• HIPOT LC: The meter will simultaneously measure output voltage and leakage
current of hipot testers up to 300 mA.
• HIPOT Timer: The meter measures the time interval of hipot testers up to 999
seconds.
• Help: The help guide offers basic information about the selected function.
The meter’s input terminals and function selection button are located in the lower left
corner of the front panel (See items 4 and 6 in Table 3-1 of Chapter 3).
Note
When measuring with the built-in multimeter, the meter terminals are
always connected. Measurements are taken whether the Calibrator is in
standby or operate mode.
Function Selection
To set the meter mode:
1. Press the Mode softkey to display the Available Modes menu (see Figure 4-20).
2. Using the cursor keys or rotary knob, highlight the mode.
3. Press the Select softkey or press in on the rotary knob to select the highlighted
