Internal Source Calibration (
ICAL
)
The meter is factory calibrated prior to shipment to read in millivolts. The
calibration equipment is certified to NIST standards. There is no need to
perform an internal calibration for new meter.
The internal source allows the user to scale the meter without applying a signal.
The use of calibrated signal sources is necessary to perform the internal source calibration of the meter.
Check calibration of the meter at least every 12 months. Each range must be recalibrated separately.
Notes:
1. mV input: If meter is in operation and it is intended to accept only one input range
(e.g. 0-30 mV), recalibration of other ranges is not necessary.
2. Strain gauge: If the meter is intended to accept a strain gauge bridge input, it is
recommended to use the CAL function with ratiometric compensation turned on.
3. Allow the meter to warm up for at least 15 minutes before performing the internal
source calibration procedure.
The
Internal
calibration
menu is part of the
Advanced
Features
menu.
1. Press and hold the Menu button for three seconds to access the advanced features of the meter.
2. Press the Up
arrow button to scroll to the
Internal calibration
menu (
ICAL
) and press Enter.
3. The meter displays the first input range (
15 mv
), press the Up arrow to select any other range (e.g.
100mv
. Press Enter
to start the calibration process.
Example of
Internal Calibration
for 100 mV input range:
4. The meter displays the message “
stroff
” (strain offset), short the SG+, SG- terminals and press
Enter. The
low
input message is displayed (
v lo
). Apply the low input signal (e.g. 0.00 mV) and press
Enter. The display flashes for a moment while the meter is accepting the low input signal.
5. After the display stops flashing, a number is displayed with the leftmost digit brighter than the rest.
The bright digit is the active digit that can be changed by pressing the Up
arrow button. Press the
Right
arrow button to move to the next digit.
6. Set the display value to correspond to the input signal being calibrated; typically 0.00 mV.
7. The display moves to the
high
input calibration (
v Hi
). Apply the high input signal and press Enter.
8. Set the display for the high input calibration, in the same way as it was set for the low input
calibration, typically 100.00 mV.
The graphic above shows the calibration of the 100 mV input range. The other input ranges are calibrated
in a similar way.
