GETTING
STARTED
Caution:
The meter has no power-on switch, so it will be in operation as soon as
you apply power.
If
you power off/on the meter, or perform a hard reset (press the RESET
button twice), the meter shows "RST" followed by "STRN".

CHECKING
OR CHANGING MAIN
BOARD POWER JUMPERS (Factory Set)
Important:
If you want to change the factory preset jumpers, do the following steps,
otherwise go to Section 3.3.
Disconnect the power from the unit before proceeding.
1.
Remove the main board from the case. Refer to Section 2.6.
2. Locate the solder jumpers W1, W2, and W3 (located near the edge
of the main board alongside the transformer).
3. If your power requirement is 115 V ac, solder jumpers W1 and
W3 should be wired, but jumper W2 should not. If your power requirement
is 230 V ac, solder jumper W2 should be wired, but jumpers W1 and W3
should not.
NOTE: W4 jumper is not used.
Figure 3-1 shows
the location of solder jumpers W1 through W3.
Figure 3-1. Power Jumper Detail (W1 - W3)
Figure 3-2 shows the location of jumper positions on the main board.
Figure 3-2.
Main Board Jumper Positions
S2 jumpers are for testing purposes. Do not use as reading errors may
result.
S3 jumpers are used for the following (refer to Table 3-2):
* To enable or disable the front panel push-buttons
* To allow for an extremely low resistance load for analog output
* To disable the MENU button
* To perform calibration procedure
Test pins TP1 - TP11 are for testing purposes. Do not use as reading errors
may result.

PANEL
MOUNTING
1.
Cut
a hole in your panel, as shown in Figure 3-4.
2. Insert
the meter into the hole. Be sure the front bezel is flush to the panel
when tightening mounting brackets..
3.
Proceed
to Section 3.4 to connect your sensor input and main power.

CONNECTING SENSOR INPUT
Figures 3-5
shows excitation supplied from the meterÆs internal supply (50mA maximum).
Select 5, 10, or 12 volt excitation at DIP switch.

Figure 3-6 shows the
connections required for an externally-powered bridge input: the external
supply is brought to the meter's buffer circuits to permit ratiometric
readings. Set S1 DIP switch for external excitation for Figures 3-6 and
3-7.

CONNECTING
MAIN POWER
Connect
the ac main power connections as shown in Figure 3-10.
WARNING:
Do not connect AC power to your meter until you have completed all input
and output connections. Failure to do so may result in injury!
Connect the DC
main power as shown in Figure 3-13.
