• Apply the values that follow:
mA: -55, -25, -20, -10, -5, 0 (open circuit)
mA: 0, 5, 10, 20, 25, 55.
• Check the error is in the specified limits (See
Table 5-2
).

PROCEDURES: CURRENT (source) 5.6
When recalibrating measure and source functions for this range, the
measure function must be adjusted before the source function.
Do the procedure as follows:
1. Connect the applicable calibration equipment
(See
Table 5-1
):
• CH1 (24 mA range): (See Table 5-3).
2. Let the equipment get to a stable temperature (minimum: 5
minutes since the last power on).
3. Use the calibration menu (
See Section 5.4
) to do a two-point
calibration (0.2 mA and FS):
• CH1: 24 mA.
4. Check the calibration is correct:
• Select the applicable Current (source) function
• Apply the values that follow:
mA: 0.2, 6, 12, 18, 24
• Check the error is within limits (
See Table 5-3
)
