Model 3001 Survey Meter Setup Mode

Setup Mode

• Designed for advanced users or administrators to change parameters.
• Incorrect settings may compromise user safety.
• Instrument undergoes electronic checkout, a 24-hour burn-in, and careful calibration before shipment.

Calibration and Recalibration

• Calibration papers included with each instrument.
• Recommended to recalibrate after maintenance or adjustments, not typically necessary after cleaning or battery changes.
• Recalibration does not require special tools.
• Full-service repair and calibration available for both Ludlum and other manufacturers' instruments.
• Recalibration suggested at annual intervals; comply with local regulations regarding calibration frequency.

Setup Parameters Overview

• Calibration constants are specific for various models, including Model 133-6, Model 44-2, Model 42-31H, and Model 44-132.
• Dead Time Correction settings, dead time can affect measurement accuracy.
• Efficiency settings specify alpha (20) and beta (15) values.
• High Voltage Setpoints vary by model, ranging from 550 to 1200 volts.
• Discriminator Threshold: Set predetermined threshold levels for detection across models.

Alarm Settings

• Loss of Count Alarm varies by type (Alpha: 600; Beta: 60).
• Detector Enable functionality can be enabled or disabled.
• Alarm values can be customized for each unit in terms of counts and minimum display.

Unit Display and Measurement Settings

• Units of measurement for various metrics (e.g., mR/h, µR/h, cpm).
• Maximum display values defined with specific upper limits for each unit.
• Ability to disable certain alarm modes when not in use.

Getting Started Instructions

• Includes unpacking procedures and verifying inventory against the packing list.
• Ensure calibration certificates match individual items.
• Serial numbers located on the unit's front side for identification.
• Return procedures require proper packing and an Instrument Return Form available on the Ludlum website.

Battery Installation

• Low-battery indicator alerts users when less than 16 hours of battery life remains.
• Replacement procedure involves turning the instrument upside down and accessing the battery compartment.

• Replacement procedure involves turning the instrument upside down and accessing the battery compartment.

Detector Current Overload Threshold

• Default setting is 100; tap ON/ACK to select and MODE to adjust the value.
• Setting to 0 disables the Current Overload Alarm.
• Value can be adjusted in ones, tens, and hundreds places (0-9).

Loss of Count Alarm Time

• Default time is 60 seconds; adjustable through ON/ACK and MODE.
• Setting to 0 disables the alarm.
• Options for adjustment available in seconds (ones, tens, hundreds places).

Primary RATE/MAX Units and Minimum Display

• Default display is 0 µR/hr; use ON/ACK and MODE to adjust.
• Adjustment should be higher than the Turn On value.

Sigma Audio

• Default is OFF; use MODE to enable or disable.
• ON status activates Sigma Audio, OFF activates normal click audio.
• Requires an 8-second background count; device beeps until acceptable range (500 cpm - 200 kcpm) is obtained.
• Disabled in Count Mode; if both Count and Sigma Audio are on, Count audio will be click.

Dual Level Audio

• Default setting is OFF; adjusted via MODE.
• ON enables Hi, LO, and Mute audio settings; OFF limits to Hi and Mute.

Datalogging Mode

• Default is 1; indicates current datalogging mode.
• Users can measure in dpm/100 cm² by manipulating efficiency based on detector area.
• Example: for 15 cm² detector with 10% efficiency: change to 1.5% for dpm/100 cm².

High Voltage Adjustment

• Default voltage is 900 Volts; adjustable using ON/ACK and MODE.
• Options available in ones, tens, hundreds places, with k Multiplier (on/off).
• When k Multiplier is on, the left-most decimal point is activated; hundreds place limited to 0 and 1.

Pulser Threshold

• Default setting is 35 millivolts; adjust via ON/ACK and MODE.
