8.2 6244 Calibration
8.2.1 Cables and Measuring Instruments Required for Calibration
The following table shows the cables and measuring instrument accuracy required for calibration in each
range.
8.2.2 Safety Precautions
(1) Use an AC power supply with the specified voltage.
(2) Set the Line Frequency to 50 Hz or 60 Hz to match the line frequency.
(3) Calibrate the 6243/44 under the following conditions in a location free of dust, vibrations, line noise,
etc.
Temperature: 23C  3C
Relative humidity: 70% or lower
(4) Wait for 2 hours or longer for warm-up to accurately calibrate the 6243/44.
Allow the measuring instruments to be used for the calibration to warm up for the period of time spec-
ified for the instruments.
The 6581 requires a warm-up time of 4 hours or longer.

*1: Use the 6581 under the following conditions.
Integration time: 20 PLC. Auto ZERO: ON. Within 24 hours following INT CAL.
*2: When much externally induced noise exists, use a shielded cable like A01001, etc.
*3: The 3.2 A range and the 10 A range are calibrated with a standard resistor and voltage value conversion.
