ABOUT
THE METER
DESCRIPTION
The Strain Meter
is a value packed
indicator/controller.
Four full digits
and broad scaling
capability allow
for display in virtually
all engineering units.
A wide variety of
current and voltage
input ranges cover
typical pro c e s
s applications. Standard
features include
sensor excitation
and front panel or
remote tare. Your
meter may be a basic
indicator or it may
include analog output
or dual relay output.
Analog or dual relay
output must be ordered
at time of purchase.
Analog output is
fully scalable and
may be configured
as a proportional
controller, or to
follow your display.
Dual 5 amp, form
C relays c o n t
rol critical processes.
A mechanical lockout
has been included
to guard against
unauthorized changes.

BUTTONS
SETPTS BUTTON
- In the run mode,
this button will
sequentially recall
the previous setpoint
settings. As necessary,
use the  /NT/GRS
and  /TARE
buttons to alter
these settings, then
press the SETPTS
button to store new
values.
Unless you press
the SETPTS,
/TARE
, or the /NT/GRS
button within 20
seconds, the meter
will scroll to setpoint
2 and then to the
run mode.
/NT/GRS
BUTTON
- In the run
mode, this button
will toggle between
net/gross readings
or peak readings,
depending upon your
setup.
In the configuration
mode, press this
button to change
the value of the
flashing digit shown
on the display and/or
toggle between menu
choices, such as
"R.1=R" or
"R.1=N". When
configuring your
setpoint values,
press the /NT/GRS
button to advance
the flashing digit's
value from 0 to 9
by 1.
/TARE
BUTTON
- In the run
mode press the /TARE
button to
tare your reading
(zeroing).
In the configuration
mode, press this
button to scroll
to the next digit.
MENU BUTTON
- In the
run mode, press the
MENU button
to terminate the
current measuring
process and enter
you into the configuration
mode
(Note: only
if you have installed
the lock out jumpers
on the main board).
In the configuration
mode, press the MENU
button to store changes
in the nonvolatile
memory and then advance
you to the next menu
item.
RESET BUTTON -
If you hard reset
(press the MENU
button followed by
the RESET
button) or power
off/on the meter,
it shows "RST",
followed by "STRN".
In the run mode,
press the RESET
button to reset the
latched setpoints.
The meter shows "SP.RS"
and returns to the
run mode (also reset
tare).
In the configuration
mode, press the RESET
button to reset the
tare value. The meter
shows "T.RS".
In the tare mode,
press the RESET
button once to review
the previous menu.
Press the RESET
button twice to result
in a hard reset and
return to the run
mode.
Note: When
in setpoint or configuration
mode, if the meter
shows 9999 or -1999
with all flashing
digits, the value
has overflowed. Press
the /NT/GRS
button to start a
new value.

selected input type
after setting the DIP
switches (see Section
4.1, Selecting the
Input Type).
Disassembly
You may need to
open up the meter for
one of the following
reasons:
* To check or change
the 115 or 230 Vac
power jumpers.
* To install or remove
jumpers on the main
board.
To remove and access
the main board, follow
these steps:
1. Disconnect
main power from the
meter.
2. Remove the
rear case cover.
3. Lift the
back of the main board
upwards and slide it
out of the case. |
