1.2 Front Panel
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.

(Not available in Versa-portion RLP-SM)
G, Ib and oz conversion is available only when SPEC08=011 (see Section 3.4 on page 11).
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).

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
- With the unit in weigh mode, press and hold the ZERO key.
- With the ZERO key held, press and release the POWER key three times.
- 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 11.
- With the unit in weigh mode, press and hold the ZERO key.
- 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.
- 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.
- 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).
- The scale will return to weigh mode automatically. Power down the unit.
- 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.

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.
- Press the setup switch (see Figure 3-1 on page 10).
- With the unit in weigh mode, press and hold the ZERO key.
- With the ZERO key held, press and release the TARE key, then press and release the POWER key twice. The SPEC number is displayed.

4.0 Appendix
4.1 DC Battery Pack
4.1.1 Battery Pack Replacement/Installation
An optional DC battery pack (PN 108516) for the Versa-portion RLP-S/SM is available and can be purchased from RLWS to ship with the scale or retrofit in the field. The rechargeable 6V 5.0 AH battery pack allows for up to 60 hours of scale use without an AC power supply (with display set to Dimmer Level 2). It is located in the bottom of the scale base. Use the following procedure to install or replace the battery pack.
- Unplug the scale from power source.
- Place scale on its left side.
- CAUTION: Do not turn the scale upside down. Always work with the scale on its side. Damage to the load cell can occur if the scale is turned upside down.
- Unscrew the Phillips-head screws holding the battery compartment door closed.
- Unscrew the two screws holding on the battery holding bracket and remove the bracket.
- If you are removing a battery previously installed, remove the battery from its compartment, then disconnect the black (-) and red (+) electrical leads from the battery. If you are installing a new battery, go to step 6.
- Attach the red lead to the positive (+) terminal of the new DC battery pack, and the black lead to the negative (-) terminal. Place new DC battery pack in battery compartment.
- Replace the battery holding bracket and fasten it with its two screws.
- Replace the battery compartment door and fasten it with the screws removed in Step 3.
- Put the scale back upright on its feet.
- Press the POWER key located on the front of the scale.
4.1.2 Battery Charging
A fully charged battery allows for approximately 60 hours of continuous use. When the battery is low, the battery indicator light will light up. To charge the battery, plug in the AC power cord. Charge time is 8-10 hours.
