Table of Contents

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.

undercarriage of the scale.

3. Gently lift and remove the scale cover and replace the scale plat-

form.

4. Turn the scale on and short the two “TEST” jumpers on the left of

the PCB above the LCD.

5. Once the scale is in Test Mode, the display can be rotated through

the following functions by pressing :

II Set-up Procedures

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.

6. Press to save a change and to progess to the next keyword.

7. Press and to return to test mode, or press then

to return to normal operating mode.

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.
