Do not, under any circumstance, return equipment to any of AMPTEC’s facilities or
sales offices without first obtaining an RMA number (see section E) from an AMPTEC
staff member. We must obtain your full contact information in order to properly
coordinate the repair and return of the AMPTEC meter.
A-3 Setup for Preparation and Use
The following quick-step guide can be taken to power up and use the AMPTEC 720A
meter:
1) The meter may be set up to operate as soon as the power is turned on, which
can be accomplished by flipping the “ON/OFF” switch upwards on the unit’s front
panel.
2) Allow at least fifteen (15) minutes of warm up before attempting to use the
product. If the unit has been stored at a more extreme temperature, please allow
up to thirty (30) minutes of warm up instead.
a. (Optional) Perform a zero check for test lead/probe integrity:
i. Connect a set of leads/probes to the front panel via the VHI and
VLO banana jack terminals on the unit’s front panel.
ii. Short the leads/probes by touching the ends (i.e. alligator clips,
spear tips, etc.) of each cable to each other.
iii. Select the 200
Ω range on the unit’s front panel
.
iv. Reading should be within 5 display counts of zero.
Your 720A meter should be ready to use immediately following its warm up period. The
product consumes little power and generates minimal heat. It may be used in any area
where the environment does not exceed the unit’s specifications (see section B). When
possible, avoid exposing the meter to extremes of temperature, which will affect
accuracy and warm up time. One should become familiar with the basic test lead usage
and the autorange feature (if applicable) described in detail in this manual in section D-
2.4 in order to properly use the unit.
For a more detailed instructional information on how to use the 720A meter, see section
D-4.
