Basic Operation - PIE PIECAL 334Plus Operating Instructions Manual

POWER SWITCH
q
Select "mA" to display and calibrate in milliamps.
Select "% 4 to 20 mA" to display and calibrate
in percent. Select "READ VDC" to read volts
DC. Return the slide switch to the "OFF"
position when not in use.
Note:
Percent mode can also be used with chart
recorders, valves or current trips that display in
percent.
100.00% = 20.000 mA
75.00% = 16.000 mA
50.00% = 12.000 mA
25.00% = 8.000 mA
0.00% = 4.000 mA
To convert from Milliamps to Percent:
Percent = (Milliamps - 4) / 0.16
To convert from Percent to Milliamps:
Milliamps = Percent / 6.25 + 4

w SOURCE / READ / 2 WIRE SWITCH
Select "SOURCE" to output in mA or percent.
Select "READ" to read in mA or percent.
Select "2 WIRE" to simulate a 2 Wire Transmitter.
e EZ-CHECK™ SWITCH
Instantly output 4.000 mA or 20.000 mA by moving
the EZ-CHECK™ switch to the "4.00mA" /"0.0%"
position or "20.00mA"/"100.0%" position. For fast
three point checks select the "DIAL" position.
The PIECAL 334Plus will remember the last
"DIAL" value, even with the power off.
Note: The same "DIAL" value is stored for both
mA and %. The recalled value will be displayed
in the units selected.
DIAL KNOB
r
Turn the knob to adjust output level. Turn
clockwise to increase the output, counter
clockwise to decrease the output 0.001 mA
(0.01%) at a time. Push and turn the knob for
faster dialing adjusting 0.100 mA (1.00%) at a
time. Press and Hold the knob to start automatic
stepping or ramping. Double click the knob for
stepping and Ground Leak Detection setup.
EXTERNAL POWER JACK (Not Shown)
t
When used with the optional AC Adaptor, the
external power jack will eliminate the drain on
your batteries. This is handy for jobs that require
extended bench use of the PIECAL 334Plus.
See accessories (page 10) for ordering information.
Note: This feature does not charge the batteries,
it only supplies power to the PIECAL 334Plus.
CHANGING BATTERIES
Low battery is indicated by "BAT" on the display.
Approximately one to four hours of typical
operation remain before the 334Plus will
automatically turn off. To change the batteries;
remove the rubber boot, remove the battery door
from the back of the unit by sliding the door
downward. This allows access to the battery
compartment. Replace with four (4) "AA" 1.5V
batteries being careful to check the polarity.
Replace the battery door & replace the boot. All
stored configuration options are reset to factory
settings when the batteries are removed.
Note: Alkaline batteries are supplied and
recommended for maximum battery life &
performance.
