10) Connect the 2300 as shown in Figure
8-4 using the 10 amp shunt.
11)
Select the 10 amp range.
12) Apply 10.000 amps and adjust
φ
AR5
for 5.000 VDC on the DVM.
13)
Connect the 2300 as shown in Figure
8-4 using the 100 amp shunt.
14)
Select the 100 amp range.
15) Apply 100.00 amps and adjust
φ
AR7
for 5.000 VDC on the DVM.
16)
Disconnect the DVM and current
calibrator.
8-5-4. Power Calibration
1) Connect the 2300 as shown in Figure 8-7.
2) Select
φ
A and the 150 (15) volt and 1 amp
ranges.
3) Connect the DVM low lead to the
negative leg of MBC5 and the high lead to
the front leg of MBR9.
4) Apply 150.00 volts and 1.0000 amps and
adjust
φ
AR40 for 2.500 VDC.
5) Disconnect the DVM and calibrators.
8-6. Option IOX Calibration
Option IOX should be calibrated following
successful completion of the Routine
Calibration procedure of Section 8-4. In this
procedure, all measurements are made at the
IOX connector using a DC voltmeter. All
measurements are made with DVM high lead.
The DVM low lead should be connected to
the IOX connector common at pin 12.
Adjustments are accessed by removing the
bottom cover of the instrument.
Caution!
AC line power is exposed at this point. Take
precautions to avoid contact with AC power
wiring.
Note: In simultaneous TL-4/IOX
installations, adjustments are accessed from
the top of the instrument and removal of the
bottom cover is not necessary.
