CAUTION: Procedures that require working inside the scale base are to be performed by qualified service personnel only.
The Versa-portion RLP-S/SM is a multi-purpose bench scale that offers practical solutions for a full range of applications. Its
internal resolution of 1/90,000 gives you maximum precision and accuracy. Its backlit LCD display enables operators to easily
see weights. When portability is required, choose the optional rechargeable battery for over 60 hours of continuous usage. The
Versa-portion RLP-S/SM is designed to reliably operate in many environments and withstand transport from one area of the
plant to another or from one business to the next.

Setting the Default Primary Unit
1. Hold the ZERO key and press the UNITS key three times.
2. Press the POWER key to cycle through available units.
3. When the desired default unit is displayed, press the TARE key to save the setting and return to weigh mode.
2.6 G, lb and oz Conversion
(Not available in Versa-portion RLP-SM)
G, lb and oz conversion is available only when SPEC08=011 (see Section 3.4 on page 9).
1. Switch between units by pressing the UNITS key.
NOTE: (G) is the abbreviation for gross. (g) is the abbreviation for grams.

3.0 Calibration
To enter calibration mode, remove the screw on the bottom of the scale as shown in Figure 3-1. Use a small tool to press the
span setup switch located under the screw. Setup will time out to verify the switch is set to the ON position. Then, perform a
span switch state check (see Section 3.1).
Figure 3-1. Setup Switch and Bleeder Screw Locations
IMPORTANT: Pressure can build up in the scale during shipment causing an error message to display. Release built up
pressure by locating the bleeder screw (see Figure 3-1) and unscrewing 7 full turns. Leave unscrewed while scale is in use.
3.1 Software Version and Span State Check
1. With the unit in weigh mode, press and hold the ZERO key.
2. With the ZERO key held, press and release the POWER key three times.
3. The display will show the software version for two seconds, then show the current span switch state (S-ON or S-OFF).
After three seconds, the unit will return to weigh mode.
3.2 Performing a Calibration
The Versa-portion RLP-S/SM must be calibrated in grams or kilograms, and SPEC 01 and 02 must be set for the gram value (or
kg in the SM version). See Section 3.4 on page 9.
1. With the unit in weigh mode, press and hold the ZERO key.
2. With the ZERO key held, press and release the POWER key twice, then press and release the TARE key.
The display will show CAL00.
NOTE: To exit calibration at any time, press the TARE key.
3. Ensure there is no weight on the platter, then press the ZERO key to calibrate the zero point.
The display will show dashes, then CALSP.
4. Place the scale’s full capacity weight on the platter and press the ZERO key to calibrate span.
The display will show dashes, then the weight value.
NOTE: Calibration weight is full grams capacity. Full capacity values are as follows: RLP-6S = 3000 g (3 kg);
RLP-15S = 6000 g (6 kg); RLP-30S = 15000 g (15 kg); RLP-60S = 30000 g (30 kg).
5. The scale will return to weigh mode automatically. Power down the unit.
6. Calibration is complete.

3.3 Enclosure Security
After an NTEP inspector has examined the unit, security cables are installed through three bolts on the underside of the scale.
These cables prevent the unit from being tampered with by an unauthorized individual. If the cable is removed, NTEP
certification will become void.
Figure 3-2. Legal for trade seal; cable passes through three bolts
3.4 Setting the SPEC Value
The SPEC value is used to specify decimal point position, minimum display, net/gross multi-interval, resolution, weight single or
multi-interval, decimal point figure, negative weight display mask, IR mode protection (SPAN switch must be turned on to allow
calibration), start range (amount of weight that can be on the scale when it is turned on), re-zero range, manual tare
cancellation, tare subtraction, tare accumulation, auto tare, weight reset, tare auto clear, zero tracking, re-zero, and the UNIT
key function. See Table 3-1.
1. Press the setup switch (see Figure 3-1 on page 8).
2. With the unit in weigh mode, press and hold the ZERO key.
3. With the ZERO key held, press and release the TARE key, then press and release the POWER key twice.
The SPEC number is displayed.
4. To increment the SPEC setting value, press the POWER key. Refer to Table 3-1.
5. Press the ZERO key to save data and increase the SPEC count.
6. Press the ZERO key to advance to the next SPEC.
7. Press the TARE key to store SPECs and return to weigh mode.
