CONFIGURING
THE METER
Refer to Table 6-1 for a summary list of menu configuration.
SELECTING
THE INPUT TYPE ("INPT")
To select your appropriate input type signal, follow
these steps:
Note: Before proceeding, Set the input DIP switch settings at the
rear of your meter before proceeding. (Refer to Table 2-3).
1. Press the MENU button. The meter shows "INPT".
2. Press the /TARE
button. The meter flashes one of the following:
* 0-20 (for 4-20 mA dc) (default)
* 100m (for 0-100 mV dc)
* ▒50m (for ▒50 mV dc)
* 10 V (for 0-10 V dc)
* ▒5 V (for ▒5 V dc)
3. Press the /MAX
button to scroll through available choices.
4. Press the MENU button to store your selection. The meter
momentarily shows "STRD", followed by "DEC.P" (Decimal Point).
SELECTING
A DECIMAL POINT POSITION ("DEC.P")
To select a decimal
point display position.
1.
Press the MENU button until the meter shows "DEC.P"
2. Press the /TARE
button. The meter shows one of the following:
* FFFF. (default)
* FFF.F
* FF.FF
* F.FFF
3. Press the
/MAX button
to scroll between available choices.
4. Press the MENU button to store your selection. The meter
momentarily shows "STRD", followed by the next menu "RD.S.O"
(Reading Scale and Offset). Or you can press the RESET button to
abort and go back to the "DEC.P" menu.
SELECTING READING SCALE AND
OFFSET (RD.S.0)
Refer to Table 6-1 for a summary list of menu configuration.
To scale the meter to show readings in engineering units. There are two
meth-ods. One method is to scale with known inputs. Another method is
to scale without known inputs: you calculate input values based on the
transducer spec-ifications and manually enter them through the keyboard.
Scaling with Known Loads
(On-Line Calibration)
For maximum resolution, find the maximum signal that will be applied to
the meter input.
* For regular
voltage input, refer to the main body of Table 4-1 on the following
page.
* For millivolt or milliamp input, refer to the main body of
Table 4-2 on the following page.
Set the DIP switch
positions as indicated at the top of either Table 4-1 or 4-2. The numbers
1 through 8 in the top row of either table represent DIP switches 1 through
8 and the O, C or X directly below the number indicates the correct position
of each switch.
* "O" Switch
should be open or up.
* "C" Switch should be closed or down.
* "X" Switch is used to control excitation (refer to Table 2-3
to determine correct position of these switches)
Once DIP switches have
been positioned correctly, apply power. Proceed to the "RD.CF"
(Reading Configuration) and set R2 equal to the value in the right hand
column of the chart.

* Reading Configuration
To scale with known inputs: apply known loads to a transducer connected
to a meter, or simulate the transducer output with a voltage or current
simulator. To scale with known inputs, follow these steps:
1. Apply a known load equal to approximately 0% of the transducer
range.
2. Press the MENU button until the meter shows "RD.S.O".
3. Press the /TARE
button. The meter shows "IN 1" (Input 1).
Note: "IN 1" (Input 1) is the unscaled display reading at minimum
input.
4. Press the /TARE
button again. The meter shows the last stored value for Input 1.
5. Press the /TARE
button once more. The meter shows the actual signal being received.
6. Press the MENU button to store this value as "IN 1".
The meter shows "RD 1" (Read 1).
7. Press the /TARE
button. The meter shows the last stored value for Read 1.
8. Press the MAX
button to change the value of your digits.
9. Press the /TARE
button to scroll horizontally to the next digit.
10. Press the MENU button to store this value as "RD 1"
(Read 1). The meter shows "IN 2" (Input 2).
Note: "IN 2" (Input 2) is the unscaled display reading at maximum
input.
11. Apply a known load equal to approximately 100% of the transducer
range.
12. Press the /TARE
button. The meter shows the last stored value for Input 2.
13. Press the /TARE
button once more. The meter shows the actual signal being received.
14. Press the MENU button to store Input 2 value. The meter
shows "RD 2" (Read 2).
Note: "RD 2" (Read 2) is the desired display reading at Input 2.
15. Press the /TARE
button. The meter shows the last stored value for Read 2.
16. Press the MAX
button to change the value of your digits.
17. Press the /TARE
button to scroll horizontally to the next digit.
18. Press the MENU button to store this value as "RD
2" (Read 2). The meter momentarily shows "STRD", followed by
"RD.CF". Meter scaling is now complete.
Scaling without Known Loads
To scale without known inputs, calculate input values based on the transducer
specifications and manually enter them on the keyboard. The following
example assumes a pressure transducer with these specifications:
Pressure Range: 0 to 2000 PSI
Output Span: 1 to 5 Vdc
1. Determine the correct values for "IN 1" and "IN 2"
based on the transducer specifications. In most cases, "RD 1 & 2"
are equal to the minimum and maximum of the transducer output span. The
example assumes "RD 1 & 2" are equal to the pressure range of the
transducer ("RD 1" = 0000 and "RD 2" = 2000). Calculate "IN
1" and "IN 2" using the transducer output span and the following
equation:
"IN" = (Sensor
Output) x (Natural Gain) x (Multiplier)

2. Determine
the multiplier by the Input Resolution setting ("R.2" in the "RD.CF"
menu) and the input range selected. Typically "R.2=4" is suitable
for most applications.

3. Determine
"IN 1 & 2" input range and resolution. The example selects the
0 to 100 mV range and 10 uV resolution ("R.2=4").
Example:
|
"IN
1" = (1 Volt) x (1000 cts/v) x (1.000) = 1000 |
|
"IN
2" = (5 Volt) x (1000 cts/v) x (1.000) = 5000 |
|
"RD
1" = 0000 |
|
"RD
2" = 2000 |
4. Press MENU button until the meter shows "RD.S.O".
5. Press the /TARE
button. The meter shows "IN 1" .
6. Press the /TARE
button again. The meter shows the last Input 1 value, with the fourth
digit flashing.
7. Press the MAX
button to change the value of your digits.
8. Press the /TARE
button to scroll horizontally to the next digit.
9. Press the MENU button to store this value. The meter
shows "RD 1".
10. Press the /TARE
button. The meter shows the last value for Read 1.
Repeat steps 7, 8 and 9 until "RD 1", "IN 2" and "RD
2" have been displayed, verified, changed (if necessary) and stored.
USING READING CONFIGURATION
("RD.CF")
Refer to Table 6-1 for a summary list of menu configuration.
You may use Reading Configuration ("RD.CF") to configure your meter
for the following:
* To enable
or disable the front panel tare
* To set the input resolution of your meter
* To display the filtered/unfiltered signal input value
Enabling
or Disabling the Front-Panel Tare
To enable or disable the front-panel tare, follow these steps:
1. Press the MENU button until "RD.CF" displays.
2. Press the /TARE
button. The meter shows one of the following:
* "R.1=T" (Tare enabled) (Default)
* "R.1=N" (Tare disabled)
3. Press the /MAX
button to view last stored selection. Press the /MAX
button to toggle between selections.
4. Press the /TARE
button to select input resolution or press the MENU button to store
your selection and enter "S1.CF" (Setpoint 1 Configuration)
Setting the Input Resolution
of Your Meter
To set the input resolution of your meter.
1. Press the "MENU" button until "RD.CF" displays,
then press the /TARE
button twice or Press the /TARE
button from "R.1".
One of the following
displays (default is "R.2=4"):
* "R.2=4" 10
╡V for Unipolar inputs. 25 ╡V for Bipolar inputs.
* "R.2=0" 1 ╡V for Unipolar inputs. 5╡V for Bipolar inputs.
* "R.2=1" 2 ╡V for Unipolar inputs. 10╡V for Bipolar inputs.
* "R.2=2" 3 ╡V for Unipolar inputs. 15╡V for Bipolar inputs.
* "R.2=3" 5 ╡V for Unipolar inputs. 25╡V for Bipolar inputs.
Example:
3 ╡V resolution means that if you input 0-30 mV, at 30 mV the meter shows
9999.
2. Press the MAX
button to scroll through available selections.
3. Press the /TARE
button to show the filtered/unfiltered value or press the MENU
button to store your selection and enter "S1.CF" (Setpoint 1 Configuration).
DISPLAYING
