version 1.1

6.6.3 for more information.

(LIN.PT)
(LO)

An attempt has been made to place a
linearization point below zero.

Incorrect linearization point entered (must be
between zero and full scale). Refer to Using
Linearization section 8.3 for more information.

(PT.TOO)
(CLOSE)

An attempt has been made to place a
calibration point too close to an existing
calibration point.

Re-enter the calibration point. Points must be
spaced by at least 2% of full scale from each other.
Refer to Using Linearization section 8.3 for more
information.

(RES)
(LO)

The scale build is configured for less than 100
graduations.

Check the resolution (count-by) and capacity
settings.

(RES)
(HIGH)

The scale build is configured for more than
30,000 graduations.

Check the resolution (count-by) and capacity
settings.

(SPAN)
(LO)

The load cell signal range (span) is too small
for these settings.

Incorrect span weight entered (must be between
zero and full scale). Scale wiring incorrect. Wrong
load cell capacity (too large). Wrong or no calibration
weight added to scale.

(SPAN)
(HI)

The load cell signal range (span) is too large
for these settings.

Incorrect span weight entered (must be between
zero and full scale). Scale wiring incorrect. Load cell
capacity too small for application.

(ZERO)
(LO)

An attempt has been made to calibrate zero
below -2mV/V.

Scale wiring incorrect

(ZERO)
(HI)

An attempt has been made to calibrate zero
above +2mV/V.

Remove all weight from scale. Scale wiring incorrect.

12.5 Diagnostic Errors

The instrument continually monitors the condition of the internal circuits. Any faults or out-of-tolerance conditions
are shown on the display as an E type error message.

In the table below the following terms are used:

Check: This item can be checked on site by service personnel.

Return for Service: The instrument must be returned to GSE Scale Systems for factory service.


Error

Description

Resolution

(E0001) The power supply voltage is too low.

Check supply

(E0002) The power supply voltage is too high.

Check scale/cables

(E0010) The temperature is outside of allowable limits.

Check location

(E0020)

Scale build is incorrect. The number of graduations has been set too low or too
high.

Fix up scale build

(E0100) The digital setup information has been lost.

Re-enter setup

(E0200) The calibration information has been lost.

Re-calibrate

(E0300) All setup information has been lost

Enter setup and calibrate

(E0400) The factory information has been lost.

Return for Service

(E0800) The EEPROM memory storage chip has failed

Return for Service

(E2000) ADC Out of Range Error. This may be caused from a broken load cell cable.

Check BUILD:CABLE
setting. Check load cell
cable, wiring, etc.

(E4000) The battery backed RAM data has lost data.

Re-enter setup

(E8000) The FLASH program memory is incorrect

Return for Service


The E type error messages are additive. For example if instrument is running off batteries and the temperature
drops, the battery voltage may be too low. The resulting error messages will be E 0011 (0001 + 0010). The
numbers add in hexadecimal as follows:

1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - A - B - C - D - E - F

(For example, 2 + 4 = 6, or 4 + 8 = C)
