Before using the scale, carefully read, understand and follow the “Safety Instructions” described in this manual. Observe the advice given
in the “Operations” section to ensure proper operation. Keep this operation manual handy for reference.
1) This scale is not an explosion-proof model. Do not use the scale in an atmosphere containing flammable gases or explosive fumes. A
fire or an explosion can result.
2) Do not operate the scale if there is smoke or a burned smell coming from the scale. Unplug the scale immediately. After making sure that
there is no danger, consult your dealer. Never try to repair the scale by yourself.
3) Never step on or sit on the scale. Not only will the scale be damaged, but you may also be injured.
4) Place the item to be weighed in the center of the platform. Items placed on the edge of the platform may fall off and cause injury.
5) When weighing a heavy, large or unbalanced item, make sure the item is stable on the platform, otherwise, an accident may occur.
6) When carrying or moving the scale, be sure to hold it by the bottom of the base with both hands. If you hold it by the platform, the plat-
form or the platform support may become detached causing the scale to fall. This will damage the scale. The platform is designed for
easy removal and cleanup.
7) Do not insert your finger into the gaps or holes in the scale. You may be injured.

PPC-200W Technical Manual
I Introduction
The PPC-200W is available in four capacities. It displays units of either kilograms and one of the fol-
lowing three: continuous pounds, continuous ounces, or pounds and ounces. The specifications for
each capacity are in the following table.
Additional specifications are provided in the operator’s manual. It is important to note that various fac-
tory parameter settings depend upon the mode (continuous pound, continuous ounce, or pound and
ounce) option selected when the scale was purchased. See section IV.D for the standard settings
for each mode.
The PPC-200W is not washdown with the optional AC adaptor or the analog meter.
Remove the batteries when operating the scale with the AC adaptor. Use only the AC adaptor supplied
or an adaptor of the same output characteristics.

II.C System Parameter Mode
1. Enter Test Mode (see section II.A for details.)
2. Press and to enter System Parameter Mode. The
scale will indicate a keyword followed by it’s value.
3. To select the desired keyword, use the keys as follows:
- increase keyword by one
+ - decrease keyword by one
Note: Use the System Parameter List in Section IV.B to locate
the function to be changed and it’s standard value.
Example: To select zero tracking time press eight
times.
4. User parameters are also set in the System Parameter Mode.
Press to cycle through system keywords 30 through 40.
After system keyword 40, user keyword 01 is displayed. Pressing
will continue to cycle through user keywords 01 through 09
and then return to system keyword 30.
Note: Use the User Parameter List in Section IV.A to locate the
function to be changed and it’s standard value.

II.D Calibration Mode
1. Enter Test Mode (see section II.A for details.)
2. Press and to enter Calibration Mode. The scale will
indicate three-point or two-point span adjustment mode and the
fraction (i.e. - 0/2, 1/2 or 2/2 for three-point) of full-scale, in kilo-
grams, that should be placed on the platform.
3. If the scale is in two-point span adjustment mode, press to
enter three-point mode.
4. Clear the platform and press .
5. Place one-half of the full scale weight (in kilograms) on the plat-
form.
Example: If the scale capacity is 5 kg/10 lb, place 2500 g on the
platform.
6. Press .
7. Add sufficient weight to the platform to bring the total to the full-
scale weight in kilograms.
Example: If the scale capacity is 5 kg/10 lb, place an-
other 2500 g on the platform for a total of 5 kg.

8. Press to save the new calibration points and return
to Test Mode. Internal counts should read 20000 +/- 3.
9. Press at any time in the span-adjustment to exit to
Test Mode without saving any new calibration points.
10. Press then to return to normal operating
mode.

2. Enter Calibration Mode (see section II.C for details.)
3. Press and to enter Factory Parameter Mode.
The steps are the same as in System Parameter Mode
(see Section II.B) with the exception that the keywords
progress from 51 through 99.
