Getting Started
______________________________________________________________________
Powering the Meter
The ST-4000 can be powered either by the internal rechargeable Ni-MH batteries or by use of
the included power supply/battery charger.
A) Using the external AC power supply: Make sure that the available AC line
voltage is 110-120V, 60 Hz. Connect the DC output plug from of the adapter /
charger to the DC receptacle on the bottom of the ST4000 meter.
B) Powering the meter with internal batteries: In order for the ST4000 meter to
operate from the internal batteries, a sufficient charge must exist on the batteries.
The recommended time to fully charge the batteries is 12 hours. Only use the
power supply / battery charger included with the meter. The batteries charge
whether the meter is switched on or off. The Red LED on the meter will illuminate
whenever the power supply / battery charger is attached and plugged into an
110VAC source.
Warning: Use Only The Power Supply / Battery Charger Supplied With The Meter.
Use Of Any Other Will Void Warranty and Can Cause Damage Or Injury.
Quick Use Instructions
To become familiar with the basic operation of the meter it is suggested that the user initially try
the following:
1) Charge the batteries using the supplied power supply/charger unit.
2) Turn the meter on by pressing the On/Off key and check settings in the Set Up menu as
described in Section 1.
3) Check and set the meter to read either CATV or VHF/UHF channels as follows:
i) From any menu screen Press CLR then Press 2, then Press ENT. The display will
show CH002 if the meter is set for CATV channels or CH02 for VHF/UHF channels.
To switch back and forth between CATV and VHF/UHF channels, perform the
following steps below, otherwise skip to step 4:
ii) Press the On/Off key to turn the meter off
iii) Press and hold the SCAN key while pressing the On/Off key
iv) The meter has turned back on and switched between the CATV and VHF/UHF
channels. Repeating steps ii and iii will switch the selected channels again.
4) Carefully align the threads and connect the G-F81 type adapter to the RF Signal input port
on the meter. Hand tighten until the adapter is fully seated. Over tightening the adapter
with a tool can seriously damage the input port on the meter.
5) Connect the CATV or VHF/UHF signal source (cable line, antenna, etc) under test to the
meter.
6) Press “” or “” to scroll through the available channels and note the measured video
signal levels.
7) To switch and display the measured Audio level or V/A differential level values instead of the
Video level, press the 0/2
nd
F key and then press the 3/ V/A key.

2 Selecting CATV or VHF/UHF Channels
The meter can be switched between CATV channels and VHF/UHF channels. To determine
how the meter is currently configured or to make a change, do the following:
From any menu screen Press CLR then Press 2, and then Press ENT.
Check to see whether the displayed channel is CH002 (CATV) or CH02 (VHF/UHF).
To switch back and forth between CATV and VHF/UHF channels, perform the following steps:
i. Press the On/Off key to turn the meter off
ii. Press and hold the SCAN key while pressing the On/Off key
iii. The meter has turned back on and switched from either CATV to
VHF/UHF or from VHF/UHF to CATV channels. Repeating steps i and ii
will switch the selected channels again.
3 Configuring Channel Line Up
The meter is factory programmed to read CATV channels 2-136 and VHF/UHF channels 2-69.
Customized CATV and VHF/UHF channel plans within these ranges can also be saved in the
“User Plan” mode.
In order to select or edit the “User Plan” channels, the meter must first be set to the proper
channel format (CATV or VHF/UHF). If you are unsure which channel format is currently
selected or want to change the selection, refer to Section 2.
3.1 CHANNEL PLAN
Select the factory programmed channel plans “NTSC CATV” or the custom “User Plan”
Press the 0/2
Press “” or “” to point “” to “Channel Plan”. Press ENT key.
Use “” or “” to select the desired plan. Press ENT key.
LCD will display:

Specific channels can be included or removed from the “User Plan”.
Press the 0/2
Press “” or “” to point “
Use “” or “” to select the desired channel. Pressing SET will toggle the display between
ON (including the channel in the plan) and OFF (eliminating the channel from the plan).
Press “” or “” to move to the next channel. Press ENT key.
Repeat the process with the SET key to toggle the channel ON/OFF setting

4 Meter Calibration
This meter has been factory calibrated. The user can recalibrate each individual channel by
connecting a CATV or VHF/UHF signal source with a known RF level to the meter input. The
factory calibration of all channels can also be restored at any time.
4.1 CORRECT CH dB (Calibration)
Adjust the displayed power level to match the input signal source level as follows:
Press the 0/2
Press “” or “” to point “” to “Correct CH dB”. Press ENT key.
Use “” or “” to adjust the displayed LEVEL value to match the input signal source.
Press SET to save the calibration. Press “ ” or “” and repeat for the next channel.
LCD will display:
CH to correct Video Carrier (V) Current correction (offset) value
